Hawaiiwith kids

It’s a US state, not a foreign trip

If you’re flying from the mainland, this is domestic travel — no passport, no customs form, no currency exchange. You do need a REAL ID-compliant driver’s license or passport to clear TSA, same as any other US flight. The one procedural quirk: agricultural inspection. Hawaii is protecting itself from invasive species, not the other way around, so there are restrictions on bringing certain fresh fruit, plants, and soil out of the state when you fly home to the mainland. Pineapples and a handful of pre-cleared items are fine; ask at the airport agriculture inspection station if you’re unsure. There’s no inspection when flying between islands.

Oʻahu and the Big Island are genuinely different trips

Oʻahu is the urban, developed island — Waikiki is a dense strip of high-rises, and Honolulu is a real city. Twenty minutes outside town you’re in rainforest or on a nearly empty North Shore beach, but the contrast between “city” and “nature” is sharp and close together.

Hawaiʻi Island (the Big Island) is the opposite: enormous, rural, and still geologically alive. It’s larger than all the other Hawaiian islands combined, has its own microclimates ranging from lava desert to rainforest to near-alpine, and is home to an active volcano system inside Hawaiʻi Volcanoes National Park. Distances are bigger and traffic is lighter. Splitting the trip the way we did — a few days of city-and-surf energy, then a few days of a slower, wilder island — worked well as a pair.

The honest downsides — there really weren’t many

We came home without much to complain about. It’s a genuinely easy, low-friction trip to do with kids — you can set your own pace, and it’s easy to find things that suit any kid’s interests, whether that’s food, tide pools, hikes, creatures, or just resort time. The food especially is an easy palette for kids, and the whole vibe is different from a mainland US beach town in a way that made the trip feel like a real “getaway” rather than just a warmer version of home.

If there’s one genuine gripe, it’s the airports: expensive, with pretty mediocre food options. Grab something before you head in rather than counting on a real meal once you’re there. TSA itself, on the other hand, was easy and fast both times — no complaints on that front.

Book early

• Flights and both hotels. Waikiki beachfront properties and Kohala Coast resorts both fill up, especially around summer break and winter holidays.
• Anything with a hard capacity limit: the luau, the submarine tour, the Kualoa Ranch ATV tour, dolphin lagoon time if your resort limits it.

Weather

Hawaii doesn’t really have a cold season — expect daytime temps roughly 75–88°F (24–31°C) year-round on the coast, with humidity that makes it feel warmer. The real seasonal split is wet vs. dry: November–March is the wetter, higher-surf season (especially on north- and west-facing shores), while April–October is drier and calmer. Higher elevations (Volcano area on the Big Island, the interior of Oʻahu) run noticeably cooler and wetter than the coast — pack a layer even in summer if you’re heading up to Hawaiʻi Volcanoes National Park.

Money

Hawaii runs on the US dollar and cards are accepted everywhere in resort areas; carry some cash for food trucks and small local spots, several of which are cash-only or card-with-a-fee. Expect meals, groceries, and gas to run noticeably higher than mainland prices — everything gets shipped in.

Getting to Hawaii, and between islands

Flying in from the mainland is a normal domestic flight — no passport needed. Getting between islands is its own short hop, not an extension of your inbound flight unless you book it that way. We flew Oʻahu → Hawaiʻi Island partway through the trip.

Hawaiian Airlines and Southwest Airlines both fly nonstop between Honolulu (HNL) and Kona (KOA) multiple times a day; the flight itself is only about 45 minutes, though you should budget real time on both ends for airport security and bag claim — interisland terminals in Hawaii can be slower than the short flight time suggests. There’s no agricultural inspection for this leg (that only applies when leaving the state). Book the interisland leg directly with the airline; Southwest in particular runs frequent short-notice interisland sales.

Island hopping, in more detail

A few things that make the HNL → KOA leg feel different from a normal domestic connection:

• Despite being a 45-minute domestic hop, it’s still a full TSA screening. There’s no shortcut because it’s “just interisland” — plan on going through security exactly like any other flight.
• Arrive at least 90 minutes early. Interisland gates at Honolulu’s Daniel K. Inouye International Airport can be in a different terminal area than the one you land in on your inbound mainland flight, so don’t build a tight connection around a best-case walk between gates. TSA PreCheck helps if you have it.
• Hawaiian Airlines is the dominant interisland carrier — it’s flown these routes since 1929, runs about 170 daily interisland flights, and mostly uses Boeing 717s (roughly 120 seats) with flight times of 20–50 minutes depending on the route. Reliability tends to run higher than Southwest’s interisland service, which is worth factoring in if a missed connection would blow up a same-day tour booking.
• Bags are simple on this leg. Hawaiian doesn’t charge for a normal checked bag on interisland flights (extra or oversized bags do incur a fee); Southwest’s standard two-free-checked-bags policy applies here too.
• Factor in the “shoulders” of the flight, not just the flight itself. Hotel checkout, the drive to the airport, security, boarding, landing, and bag claim on the other end typically add up to more total time than the 45 minutes in the air — treat it like a half-day transition, not a quick hop.

Oʻahu: the rental car

We rented a Chevrolet Camaro convertible from Voyage Rental Cars, a small independent agency near our hotel in Waikiki. Pickup was easy and parking was free, though the garage has limited hours — worth checking before you plan a very early or very late pickup/drop-off. A convertible was genuinely a fun call for Oʻahu’s mix of coastal highway and North Shore driving, though it’s not the most practical if you’re hauling beach gear or car seats for more than two kids.

Hawaiʻi Island: the rental car

We picked up a car from Budget Car Rental at Kona International Airport (KOA), the standard airport-counter option. On the Big Island a car is close to essential — distances between sights are large (it’s roughly two hours from the Kohala Coast to Hawaiʻi Volcanoes National Park), and public transit doesn’t cover most visitor destinations.

Grocery runs

Having a car on both islands meant we ended up doing regular grocery store runs — stocking up for hikes, beach days, and just snacking back at the hotel rather than paying resort prices for everything. Worth building into the itinerary rather than treating it as a chore:

• Don Quijote (“Donki”) — a Japanese discount superstore with locations on Oʻahu, and genuinely worth a dedicated visit, not just a quick stop. Huge selection of Japanese and local snacks, drinks, and prepared food at better prices than resort-area shops.
• 7-Eleven — Hawaii’s version leans hard into local and Japanese-style food, well beyond mainland 7-Eleven fare. A salmon onigiri/rice ball was a repeat favorite (we never caught the exact product name — if you spot it, it’s worth grabbing).
• Shrimp chips and other local snack brands turned into a running favorite in the car and at the hotel.
• Stocking up on drinks at a grocery store rather than buying them at the beach or the resort added up to real savings over 10 days.

The Royal Hawaiian — Waikiki

The famous “Pink Palace of the Pacific,” beachfront on the Waikiki strip and open since 1927 — there’s real history here, not just a pink paint job. What stood out:

• The Mai Tais were genuinely excellent — this is one of the hotels that claims to have originated the drink, and the bar leans into it.
• Breakfast with an ocean view was a highlight of the mornings — the pink pancakes in particular were a hit with the kids.
• Free daily classes — lei making, koi feeding — gave the kids something low-key to do most mornings without leaving the property.
• Location is the whole value proposition. Central on the Waikiki strip, walking distance to an enormous amount of food and shopping.

Hilton Waikoloa Village — Kohala Coast

This is less a hotel and more a resort-as-destination — budget real time here, not just a place to sleep between excursions. The property sprawls across 62 oceanfront acres and includes:

• A large ocean-fed saltwater lagoon — protected from the open ocean’s rougher surf, and genuinely full of marine life: sea turtles, eels, rays, and reef fish all in swimming distance of the beach chairs.
• Canals running through the property with large ocean fish visible from the walkways (and connected by a monorail/canal-boat system between the towers — worth riding at least once just for the novelty).
• A separate dolphin lagoon, where we swam with dolphins.
• Multiple pools and waterslides.
• Rentable water activities: paddleboards, sea hammocks, kayaks, and water trikes.

The kids didn’t want to leave the property most days, which tells you most of what you need to know.

Manoa Falls Trail

A gentle rainforest hike — about 1.5–2 miles round trip, roughly an hour or two depending on stops, and forgiving enough for kids. The trail climbs through banyan and bamboo groves to a 150-foot waterfall, and the jungle setting will look familiar: parts of Jurassic Park and Lost were filmed here. Parking at the trailhead runs a small fee; the trail is often muddy, so shoes you don’t mind getting dirty are the move.

Mauka Warriors Luau

Held at Coral Crater Adventure Park in Kapolei, this luau leans into Polynesian warrior history rather than the more generic luau format — demonstrations, theatrical tributes, and cultural dances built around the history of Polynesian conflict and King Kamehameha’s campaign to unite the islands. Food was fine, not the highlight, but the experience and the number of hands-on activities for kids made it worthwhile.

Shark’s Cove

One of the best easy snorkeling spots on the island, tucked into Pupukea on the North Shore, directly across from a Foodland grocery store. Calm, reef-protected water inside the cove made for great fish- and creature-spotting with the kids.

Laniakea Beach

A well-known spot to see Hawaiian green sea turtles (honu) hauled out on the sand — we stopped to watch rather than swim. Volunteers sometimes rope off areas around resting turtles; keep your distance regardless (see the safety section — it’s a federal protection, not a suggestion).

Kualoa Ranch — ATV tour

A 4,000-acre working cattle ranch on the windward side that’s also one of Hollywood’s most-used Hawaii filming locations (Jurassic Park, Jumanji, Godzilla, Lost, and dozens more). We booked a guided ATV tour through the Kaʻaʻawa Valley — genuinely informative guide, great views, and the kids enjoyed it more than expected. Guides are happy to stop for photos along the way.

Byodo-In Temple

A serene, non-denominational Buddhist temple inside the Valley of the Temples in Kāneʻohe — a scaled replica of a 950-year-old temple in Uji, Japan, built in 1968 to mark the centennial of Japanese immigration to Hawaii. The koi pond is a highlight for kids (feeding is often possible), and the grounds are quiet and genuinely beautiful.

We also picked up sand art from a local artist working near the temple, credited to Wang Ge. Turns out she’s a known Beijing-trained “cloisonné sand painting” artist — gold-wire outlines filled with brilliant colored sand, mostly Asian and Hawaiian nature scenes — who moved to Hawaii in 2017 and keeps a stand at Byodo-In as well as a permanent gallery in Waikiki: Wangge Gallery, 2424 Kalākaua Ave, Suite 135, Honolulu, HI 96815, (808) 639-1378. Worth a stop if you liked what you picked up at the temple.

Matsumoto Shave Ice

The North Shore institution, in business since 1951 and credited with introducing shave ice’s most iconic Hawaii form. Located in the Haleiwa Store Lots at 66-111 Kamehameha Hwy. Expect a line, but it moves fast.

• Manoa Falls TrailMānoa, Honolulu · trailhead parking on Mānoa RdEasy 1.5–2 mile rainforest hike to a 150-ft waterfall. Small parking fee, gets muddy.
• Mauka Warriors LuauCoral Crater Adventure Park, 91-1780 Midway Rd, KapoleiWarrior-history-focused luau. Good activities for kids, food just okay.
• Shark's CovePupukea, North Shore — across from FoodlandEasy, reef-protected snorkeling. Water shoes essential; summer only for safety.
• Laniakea BeachNorth Shore, Kamehameha HwyReliable spot to see resting green sea turtles from shore.
• Kualoa Ranch49-560 Kamehameha Hwy, Kāneʻohe4,000-acre ranch and film location. ATV tours 16+, horseback 10+.
• Byodo-In Temple47-200 Kahekili Hwy, KāneʻohePeaceful Buddhist temple replica with a koi pond kids can feed. Modest dress expected.
• Matsumoto Shave Ice66-111 Kamehameha Hwy, HaleʻiwaThe North Shore shave ice institution since 1951. Long line, moves quickly.

Waikiki turned out to be an unexpectedly great food base — dense enough that most nights we just walked. A few standouts: Musubi & Bento IYASUME was legitimately locally recommended and good enough that we picked up extras for day trips; Ramen Bario Waikiki was the trip’s favorite ramen for one of the kids, while Nana Musubi’s onigiri was another high point. On the North Shore, Pupukea Grill, the food truck right across from Shark’s Cove, was the perfect post-snorkel stop — garlic shrimp and rice never tasted better than after a morning in the water.

• Musubi & Bento IYASUME (Waikiki Seaside)334 Seaside Ave, HonoluluLocally recommended musubi — legitimately excellent, worth grabbing extra for day trips. Grab-and-go counter, wide variety of onigiri plus daily bento sets.
• Nana Musubi2250 Kalākaua Ave, Waikiki Shopping Plaza (STIX ASIA food hall)Top-notch onigiri, made fresh and warm all day with organic Japanese rice. Also does a good tonjiru pork-and-vegetable miso soup on the side.
• Ramen Bario Waikiki2250 Kalākaua Ave, STIX ASIA food hallOne kid's favorite ramen of the whole trip — a Waikiki branch of the Japan-based Ramen Bario chain, known for rich tonkotsu pork-bone broth.
• Tsurutontan Waikiki2233 Kalākaua Ave, Royal Hawaiian CenterPopular, well-loved udon spot — oversized bowls of fresh, handmade udon made daily on-site. Lively izakaya atmosphere; expect a wait at peak times.
• Udon Yama2250 Kalākaua Ave, STIX ASIA food hallSimple, easy udon — a good option for a picky eater. Handmade Sanuki-style noodles; look for the pink udon made with ube worked into the dough.
• Maguro Brothers Hawaii (Waikiki)2250 Kalākaua Ave, Waikiki Shopping PlazaExcellent, fresh poke and sashimi from a counter-service seafood market — locally caught tuna, Japanese- and Hawaiian-style. Evenings only, closed Sundays.
• Paia Fish Market (Waikiki)2299 Kūhiō Ave, HonoluluFresh, well-prepared fish plates from the Waikiki branch of the Maui-born chain — mahi mahi, ono, and ahi as tacos, fish-and-chips, or blackened sandwiches.
• Rainbow Drive-In3308 Kanaina Ave, HonoluluThe classic Hawaii plate-lunch experience — worth doing at least once. The original 1961 location; famous for the mixed plate over rice with mac salad.
• Waikiki Food Hall2201 Kalākaua Ave, Royal Hawaiian Center, 3rd floorBig, varied food hall near the hotel — popular with the kids for the range of options, from Okinawan-style musubi sandwiches to garlic shrimp.
• Waffle and Berry2250 Kalākaua Ave, Waikiki Shopping PlazaWaffles, a good breakfast/brunch option — Liège-style Belgian waffles and açaí bowls piled with fresh berries.
• Nana's Green Tea2250 Kalākaua Ave, STIX ASIA food hallJapanese tea and matcha desserts from a Tokyo-based chain — high-grade Uji matcha drinks, soft-serve, and parfaits.
• Mitsuwa Marketplace2330 Kalākaua Ave, International Market PlaceJapanese grocery and snack stop — good for stocking up on car/beach-bag snacks, plus a well-regarded ramen counter and bakery for a quick meal.
• Island Vintage Shave Ice2201 Kalākaua Ave, Royal Hawaiian CenterAnother solid Waikiki-based shave ice option — organic, real-fruit syrups instead of artificial ones, with toppings like mochi and haupia.
• Pupukea Grill59-680 Kamehameha Hwy, Pupukea — across from Shark's CoveGarlic shrimp and rice after a morning of snorkeling — great timing, great food. Run by the same family since 2008; the ahi loco moco is worth trying too.
• Haleʻiwa Beach House62-540 Kamehameha Hwy, HaleʻiwaRelaxed dinner spot with a great sunset view over the water, right across from Haleʻiwa Aliʻi Beach Park — a nice way to end a North Shore day. Closed Tuesdays.

Akaka Falls

An easy, paved loop trail near Honomu to a dramatic 442-foot waterfall — one of the more accessible “big” waterfalls on the island, and genuinely manageable for kids.

Rainbow Falls

Right in Hilo, an easy roadside-adjacent waterfall — worth a stop if you’re already in town, minimal effort required.

Tide pools at Wawaloli Beach Park

A cove near the Natural Energy Laboratory of Hawaii Authority (NELHA) area outside Kailua-Kona, with tide pools that kept the kids entertained exploring for a good while.

Ocean Rider Seahorse Farm

A genuinely unique, biologist-led educational tour near the Kona airport (in the NELHA research park area) — the farm sustainably breeds seahorses and seadragons for aquariums and research rather than pulling them from the wild. The highlight: guests get to hold a seahorse, which wraps its tail gently around a finger. Reservations recommended in advance.

Submarine tour, Kona

We took an Atlantis Submarines tour departing from the Kailua-Kona pier (meeting point near 75-5660 Palani Rd) — a genuine, Coast Guard-approved passenger submarine descending about 100 feet to a 25-acre coral reef with two shipwrecks. A completely unique way to see the underwater world without anyone getting wet, and a hit with the kids.

Hawaiʻi Volcanoes National Park

The big day trip — roughly two hours from the Kohala Coast. We had lunch in the park (fine, not memorable) and spent the day exploring the crater rim areas and steam vents. Give this more than a rushed afternoon if you can; it’s a genuinely different landscape from the resort coast.

Nāhuku (Thurston Lava Tube)

Inside Hawaiʻi Volcanoes National Park — a walkable lava tube formed by flowing lava that hollowed out as its surface cooled and the interior kept draining. An easy, interesting stop most families can do without much planning.

Punaluʻu Black Sand Beach

A striking black sand beach — the sand is volcanic in origin, formed as lava meets the ocean and shatters into basalt fragments. Green sea turtles frequently rest here as well.

• Akaka Falls State ParkHonomuEasy paved loop to a 442-ft waterfall. Good for kids.
• Rainbow FallsHiloEasy roadside waterfall stop.
• Wawaloli Beach Park tide poolsNear NELHA, Kailua-KonaTide pools great for kids to explore.
• Ocean Rider Seahorse FarmNear Kona International Airport (NELHA area)Biologist-led tour; guests hold seahorses. Book ahead.
• Atlantis SubmarinesDeparts Kailua-Kona pier, near 75-5660 Palani RdReal passenger submarine to a 100-ft coral reef and two shipwrecks.
• Hawaiʻi Volcanoes National Park~2 hrs from Kohala CoastVolcanic landscape, crater rim trails, steam vents. Give it a full day.
• Nāhuku (Thurston Lava Tube)Inside Hawaiʻi Volcanoes National ParkWalkable lava tube, easy stop.
• Punaluʻu Black Sand BeachKaʻū districtVolcanic black sand beach, frequented by green sea turtles.

• Ikkyu Ramen68-1820 Waikoloa Rd, Waikoloa PlazaSolid, convenient ramen option near the resort — tonkotsu and shoyu, made-to-order broths. A rare authentic ramen spot in an area otherwise dominated by resort dining.
• Lehua Restaurant600 Imiloa Pl, Hilo — inside the ʻImiloa Astronomy CenterA good sit-down option on our Hilo day, inside the astronomy center — contemporary Hawaiian cuisine with fresh local ingredients. It's about 1.5–2 hours from the Kohala Coast, so pair it with the volcano day trip rather than a standalone drive.
• Pau Hana Poke73-5617 Maiau St, Bay 10, Kailua-KonaDelicious, made-to-order poke near Costco and the Kona airport — a rotating selection of fresh ahi in Hawaiian, spicy, and shoyu preparations. Takeout only, closed Sundays.

Ocean safety

Hawaii’s beaches are beautiful and genuinely dangerous in specific, predictable ways — most drownings and rescues involve visitors underestimating conditions they’d never encounter at home.

Rip currents are the leading cause of ocean rescues in Hawaii. If caught in one, don’t swim against it — swim parallel to shore until free of the current, then angle back in.

Tsunamis — a real, if rare, possibility

Hawaii sits in the middle of the Pacific, so tsunami warnings do happen, and coastal resorts (including ones you’re likely staying at) sit inside mapped evacuation zones. It’s genuinely worth five minutes of prep rather than something to wave off as unlikely.

Reef and wildlife

• Reef-safe sunscreen is required by law, not just a suggestion — Hawaii banned the sale of sunscreens containing oxybenzone and octinoxate in 2021 because of coral reef damage. Look for mineral (zinc oxide/titanium dioxide) formulas.
• Don’t touch, stand on, or step on coral — it’s a living organism and takes decades to recover from damage.
• Green sea turtles (honu) and Hawaiian monk seals are federally protected. Keep a distance of at least 10 feet from turtles and 50 feet from monk seals — touching or crowding them can carry real fines, and it’s genuinely harmful to animals that are already vulnerable.
• A rough rule of thumb for jellyfish: box jellyfish tend to arrive on south- and west-facing Oʻahu shores (including Waikiki) roughly 8–10 days after a full moon — check current advisories if the timing lines up with your trip.

Cultural etiquette

• “Aloha spirit” is a real, practiced value, not just a marketing phrase — patience, respect, and generosity go a long way locally.
• Don’t take lava rock or sand off the islands. Beyond the (real) ecological impact, there’s a well-known local belief that removing volcanic material invites “Pele’s curse” — bad luck attributed to the volcano goddess. Whether or not you take the folklore literally, taking material from beaches and parks is both discouraged and often illegal.
• Respect kapu (restricted/sacred) signage and private roads. Some areas — heiau (temple sites), certain trails, and private land — are closed for cultural or safety reasons. This isn’t red tape for its own sake.
• Hiking: stay on marked trails. Valley trails like Manoa are prone to flash flooding during heavy rain, and off-trail terrain is often less stable than it looks.

• Reef-safe (mineral) sunscreen — required, and easy to forget before you land.
• Water shoes — genuinely necessary for lava-rock entries like Shark’s Cove, not optional.
• A light rain layer — North Shore Oʻahu and the Big Island’s Volcano area both see real rain even in the dry season.
• A warmer layer for Volcanoes National Park — elevation there runs noticeably cooler than the coast.
• Two swimsuits per person — with pools, lagoons, and ocean all in daily rotation, having a dry suit to switch into matters.
• Reusable water bottles — tap water is safe to drink island-wide.
• Cash — several food trucks and small local spots are cash-only or prefer it.
• A dry bag — useful for the submarine tour, boat activities, and the resort’s water toys.

The mix of hands-on animal encounters (koi feeding, seahorse holding, dolphin lagoon, turtle-spotting) and low-effort, high-payoff nature (tide pools, easy waterfall hikes, calm-water snorkeling) made both islands work well for kids. The Kualoa Ranch ATV tour and the submarine tour were the two “big ticket” activities that most exceeded expectations — both delivered a genuine sense of adventure without requiring much physical difficulty.

Give every stop a story — reading a fact or two out loud before arriving turned a few of these stops from “another photo” into something the kids actually engaged with:

• Kualoa RanchOver 200 Hollywood movies and TV shows have been filmed in this one valley — Jurassic Park, Jumanji, Godzilla, and Lost among them.
• Byodo-In TempleThis temple is a smaller copy of a real 950-year-old temple in Uji, Japan, built here to mark 100 years since the first Japanese immigrants arrived in Hawaii.
• Punaluʻu Black Sand BeachThe black sand is made of lava that shattered into tiny pieces the instant it touched the ocean — the whole beach is basically volcanic glass.
• Nāhuku Lava TubeThis tunnel formed when the outside of a river of lava cooled and hardened while the lava inside kept flowing and eventually drained out, leaving the tube behind.
• Manoa FallsThe jungle around this trail looked prehistoric enough that Jurassic Park's filmmakers used it as a filming location.

Motion sickness meds are worth having on hand before the submarine tour and any boat-based activity — the ride out to the sub in particular can be choppier than the calm resort water suggests.

What went wrong

A tsunami warning hit while we were on the Big Island. We evacuated to high ground along with everyone else on that stretch of coast. It wasn’t as dramatic as it sounds in hindsight — we picked up some food and snacks, found a spot to watch the sunset, and waited it out until officials gave the all-clear, then drove back down to the hotel. Genuinely fine in the end, but it’s a real thing that can happen on a Hawaii trip, not just theoretical disaster-prep material — see the safety section above for what to actually do if it happens to you.

What we’d tell a first-timer

• Don’t try to see “all of Hawaii” in one trip. Two islands in 10 days was already a lot of driving and repacking; each island rewards slowing down more than covering more ground.
• Book the capacity-limited stuff (luau, submarine, ATV tour) well before you land — these are the items most likely to sell out, especially in peak season.
• Reef-safe sunscreen and water shoes are not optional extras — both came up as genuinely necessary, not just nice-to-haves.
