It rains in Hawai’i. A lot, actually — especially on the windward and north-facing sides of every island, and during winter months (November through March). If you’re visiting from the mainland and wake up to a gray sky, don’t panic. A rainy day in Hawaii is not a wasted day. Some of our best family memories happened when the weather pushed us indoors.
We’ve put together every indoor and rain-friendly activity we’d actually recommend across all the major islands. No filler, no “just go shopping” cop-outs (okay, maybe one). Every spot has the address, cost, hours, and parking info so you can just pick one and go.
Pro tip: Rain in Hawai’i is usually localized. If it’s pouring on the windward side, drive 20 minutes to the leeward side and it might be sunny. Check weather radar before committing to a full indoor day.
O’ahu — The Most Options
O’ahu has the most indoor activities of any island, which makes sense — it’s the most developed. Here are our picks, organized by vibe.
Museums & Culture
1. Bishop Museum
The best museum in Hawai’i, full stop. Bishop Museum is a deep dive into Hawaiian and Pacific Island culture, natural history, and science. The Hawaiian Hall is stunning — three floors of artifacts, royal heirlooms, and cultural exhibits in a gorgeous Victorian-era building. The Science Adventure Center is perfect for keiki, with hands-on exhibits about volcanoes, ocean currents, and island ecosystems. The planetarium runs daily shows that are worth the extra fee.
Plan for 2–3 hours minimum. It’s the kind of place where you keep finding new things around every corner.
📍 1525 Bernice St, Honolulu, HI 96817
💰 Adults $26.95 (weekday) / $28.95 (weekend) | Keiki $18.95/$20.95 | Military $14.95 | 🅿️ Free on-site lot | 📋 Tickets recommended online in advance
Bishop Museum Website | Buy Tickets
Hours: Daily 9am – 5pm | Phone: (808) 847-3511
2. Waikiki Aquarium
Small but charming, and one of the most affordable attractions in Waikiki. The Waikiki Aquarium has been around since 1904 and features Hawaiian monk seals, jellyfish exhibits, giant clams, reef fish, and a solid coral garden. It’s not going to take all day — plan for about an hour — but it’s perfect for a rainy morning with keiki. Right on the water near Kapi’olani Park, so if the rain clears you can walk the beach after.
📍 2777 Kalakaua Ave, Honolulu, HI 96815
💰 Adults $12 | Keiki (5–13) $5 | Under 5 free | 🅿️ Street parking / Honolulu Zoo lot nearby | 📋 No reservations needed
Hours: Daily 9am – 4:30pm | Phone: (808) 923-9741
3. Hawai’i Children’s Discovery Center
If you’re traveling with keiki under 10, this is the rainy day move. The Discovery Center has interactive exhibits where kids can pretend to be firefighters, doctors, construction workers, or grocery shoppers. It’s fully hands-on and designed for little ones to run around and explore. The “Rainbow World” exhibit teaches about different cultures through food, music, and dress-up. Not fancy, but keiki love it — and it buys you a solid 2–3 hours of entertainment.
📍 111 Ohe St, Honolulu, HI 96813
💰 $12 general / $10 kama’āina / Under 1 free | 🅿️ Free parking on-site | 📋 No reservations needed
Hours: Tue–Fri 9am–1pm, Sat–Sun 10am–3pm (Closed Mon) | Phone: (808) 524-5437
Active & Fun
4. Pickles at Forté — Indoor Pickleball
Honolulu’s first (and only) indoor, air-conditioned pickleball facility. Six courts, right in Downtown Honolulu on Fort Street Mall. Whether you’ve been playing for years or have never held a paddle, this is a great way to burn energy on a rainy day. They have drop-in play, league nights, and you can rent equipment if you didn’t bring your own.
The kama’āina rate ($15 drop-in) is solid, and they’re open until midnight on weekdays if you want a late-night session. The vibe is fun and social — you’ll end up playing with strangers and leaving with new friends.
📍 1032 Fort Street Mall, Honolulu, HI 96813
💰 Drop-in: $15 kama’āina / $25 visitor | Memberships from $100/mo | 🅿️ Street parking & nearby garages | 📋 Reserve via CourtReserve app or call
Pickles at Forté | Forté Building
Hours: Mon–Fri 6:30am–midnight, Sat–Sun 6:30am–10pm | Phone: (808) 758-4683
5. iTrampoline Hawai’i
Over 14,000 square feet of trampolines, foam pits, dodgeball courts, basketball hoops, and laser tag. If your keiki need to burn off energy and the beach isn’t an option, iTrampoline is it. The facility is in Waipahu (about 20 minutes from Waikiki), and it’s geared toward kids ages 2–14 but honestly, adults have a blast too. Buy your pass online in advance and fill out the waiver ahead of time — saves you 15 minutes at the door.
📍 94-157 Leoleo St, Waipahu, HI 96797
💰 1-hour pass ~$18.50 | 2-hour ~$25 | 4-hour ~$32 | 🅿️ Free lot | 📋 Book online to save time
Hours: Mon–Thu 10:30am–2pm, Fri 2–9pm, Sat 10am–9pm, Sun 12–7pm | Phone: (808) 200-5867
6. Escape Rooms — Chambers, Breakout Waikiki, or The Escape Game
O’ahu has several solid escape rooms, and they’re perfect for a rainy afternoon with a group. Our top picks:
Chambers Escape Games — The highest-rated on the island. Premium, immersive rooms with cinematic set design. Private bookings only, so it’s just your group.
📍 550 Halekauwila St, Honolulu, HI 96813
Breakout Waikiki — Six rooms right on Waikiki Beach Walk. Walkable from most hotels. 4.9/5 rating with 2,000+ reviews.
📍 226 Lewers St, Honolulu, HI 96815
The Escape Game — Inside Ala Moana Center. Combine it with shopping or a meal at the food court.
📍 1450 Ala Moana Blvd, Honolulu, HI 96814 (Ala Moana Center)
💰 ~$35–45/person across all three | 📋 Reservations required — book online
Shopping & Browsing (Yes, We Said It)
7. Ala Moana Center
Look — we know “go to the mall” sounds like a cop-out. But Ala Moana is the largest open-air shopping center in the world, and on a rainy day it’s honestly one of the best things to do. Most of it is covered, and beyond shopping you’ve got a massive food court (Shirokiya Japan Village Walk is worth the trip alone), a movie theater, The Escape Game, and plenty of sit-down restaurants. You can easily spend 3–4 hours here without realizing it.
📍 1450 Ala Moana Blvd, Honolulu, HI 96814
💰 Free to browse | 🅿️ Free parking (4 hours with validation, or street meters) | 📋 No reservations
Hours: Mon–Sat 10am–9pm, Sun 10am–7pm

Maui — Aquarium, Art & Culture
Maui has fewer indoor options than O’ahu, but the ones it has are world-class.
8. Maui Ocean Center
The best aquarium in Hawaii, and arguably the best in the Pacific. Maui Ocean Center focuses entirely on Hawaiian marine life — no penguins or polar bears here, just the species that actually live in these waters. The 750,000-gallon Open Ocean exhibit with a walk-through tunnel is the highlight — sharks, rays, and tuna gliding overhead. They also have a Humpback Whale exhibit (seasonal), a turtle lagoon, and touch pools for keiki. Plan for 2–3 hours.
The kama’āina weekend rate ($15 adults, $10 keiki) is one of the best deals in Maui.
📍 192 Ma’alaea Rd, Wailuku, HI 96793
💰 Adults $39.95 | Keiki (4–12) $26.95 | Under 3 free | Kama’āina weekends: $15/$10 | 🅿️ Free lot | 📋 Tickets online recommended
Maui Ocean Center | Buy Tickets
Hours: Daily 9am–5pm (until 6pm Jul–Aug) | Phone: (808) 270-7000
9. Lahaina Galleries & Art Walks
Lahaina’s Front Street has been slowly recovering since the 2023 fires, and the art galleries that have reopened are worth visiting — both for the art and to support local businesses rebuilding. On rainy days, gallery hopping is a great way to spend a few hours. Many galleries feature Hawaiian and Pacific Island artists. Check which galleries are currently open before heading out, as the recovery is ongoing.
💰 Free to browse | 🅿️ Street parking in Lahaina
10. ‘Iao Valley (Rain Makes It Better)
This one’s a bit of a cheat because it’s outdoors — but ‘Iao Valley is actually MORE beautiful in the rain. The mist rolls through the valley, the ‘Iao Needle disappears and reappears through clouds, and the green is impossibly vivid. If it’s light rain (not a full downpour), throw on a rain jacket and go. The paved trail to the viewpoint is short (0.6 miles) and manageable even in wet conditions. Just watch your footing.
📍 ‘Iao Valley State Monument, ‘Iao Valley Rd, Wailuku, HI 96793
💰 $5/person (non-resident) | Free for kama’āina | 🅿️ $10 parking | 📋 Reservations required
Reserve at gostateparks.hawaii.gov

Kaua’i — The Rainiest Island (For Good Reason)
Kaua’i gets more rain than any other Hawaiian island — Mt. Waialeale is one of the wettest spots on Earth. The locals are used to it, and there are some solid rainy day options.
11. Kauai Museum
A well-curated museum in downtown Lihue that covers Kaua’i’s geological history, Hawaiian culture, and the sugar plantation era. The building itself is beautiful — built from concrete and lava rock. It’s small enough to see in about an hour, but the exhibits are thoughtful and detailed. Great for getting context on the island before you explore.
📍 4428 Rice St, Lihue, HI 96766
💰 Adults $15 | Kama’āina $10 | Keiki (8–17) $10 | Under 7 free | Military free | 🅿️ Free street parking
Hours: Mon–Sat 9am–4pm (Closed Sun) | Phone: (808) 245-6931
12. Kōloa Rum Company — Tasting Room
A free rum tasting on a rainy afternoon? Yes, please. Kōloa Rum’s tasting room is at Kilohana Plantation in Puhi, and they offer complimentary tastings of their small-batch Hawaiian rums on the hour. The plantation grounds are also worth walking (covered lanai areas), and there’s a train ride for keiki. Everyone in your party must be 21+ for the tasting room, so this is an adults-only rainy day option.
📍 3-2087 Kaumualii Hwy, Lihue, HI 96766 (Kilohana Plantation)
💰 Free tasting (21+ only) | $5 online booking fee | 🅿️ Free lot | 📋 Tastings on the hour, last at 4pm
Hours: Mon–Sat 10am–5pm (Closed Sun) | Phone: (808) 246-8900
Big Island — Lava Tubes, Astronomy & Coffee
The Big Island has some unique rainy day options you won’t find anywhere else — including walking through a 500-year-old lava tube.
13. ‘Imiloa Astronomy Center
One of the most underrated attractions in all of Hawaii. ‘Imiloa connects Hawaiian cultural knowledge with modern astronomy — it’s at the base of Mauna Kea, and the exhibits explore how Polynesian wayfinders used the stars to navigate the Pacific thousands of years before GPS. The planetarium shows are incredible, and the interactive exhibits keep keiki engaged. Plan for 2+ hours. It’s on the UH Hilo campus, so parking is easy.
📍 600 ‘Imiloa Pl, Hilo, HI 96720 (UH Hilo campus)
💰 Adults $19 | Keiki (5–12) $12 | Kama’āina adults $14 | Under 4 free | 🅿️ Free lot | 📋 No reservations needed
Hours: Tue–Sun 9am–4:30pm (Closed Mon) | Phone: (808) 932-8901
14. Nāhuku (Thurston Lava Tube)
Walk through a 500-year-old lava tube inside Hawai’i Volcanoes National Park. It’s lit, paved, and only about a 20-minute walk — but the experience of standing inside a tube carved by flowing lava is unlike anything else. The surrounding rainforest trail is gorgeous in the rain (tree ferns, birdsong, mist). Bring a light jacket and closed-toe shoes. This is technically outdoors but you’re inside a cave, so rain doesn’t matter.
📍 Crater Rim Dr, Hawai’i Volcanoes National Park, HI 96718
💰 Free with park entry ($30/vehicle) | 🅿️ Parking at Thurston lot (fills up — arrive early or use Kīlauea Iki Overlook lot) | 📋 No reservations
NPS — Nāhuku Info | Hawai’i Volcanoes NP
Hours: Lit 8am–8pm daily | Park open 24/7
15. Kona Coffee Farm Tours
The Kona Coffee Belt on the west side of the Big Island has dozens of small farms offering tours and tastings. Most tours are covered or partially covered, making them doable in light rain. You’ll learn about the growing and roasting process, taste different roast levels, and usually walk away with a bag of fresh beans. Greenwell Farms and Hula Daddy are two popular ones with regular tour schedules.
💰 Free – $30 depending on the farm | 🅿️ Farm lots | 📋 Some require reservations
Greenwell Farms | Hula Daddy Kona Coffee

Rainy Day Pro Tips
1. Check the radar before you commit. Hawaii rain is often localized. Use Weather.gov or Windy.com to check — if it’s raining on the north shore, the south shore might be clear. Drive 20–30 minutes and you could find sunshine.
2. Pack a light rain jacket. Not an umbrella — a jacket. Wind + rain + umbrella = bad time. A packable rain shell from REI or Patagonia takes up zero space in your bag.
3. Waterfalls are better in the rain. Seriously. Manoa Falls on O’ahu, Wailua Falls on Kaua’i, Akaka Falls on the Big Island — they all rage after rain. Just be careful on muddy trails and skip anything with stream crossings if it’s been raining hard.
4. Morning rain often clears by afternoon. Don’t cancel your whole day because of a morning shower. Do an indoor activity in the morning, and you might get a sunny afternoon.
5. Embrace it. Some of the most beautiful moments in Hawaii happen when it’s raining. Rainbows come out right after. The green gets greener. The waterfalls roar. Rain is part of the experience here.
Rain or Shine, Hawaii Delivers
A rainy day in Hawaii is not a wasted day. Whether you’re smashing a pickleball at Forté, walking through a 500-year-old lava tube, or watching sharks at Maui Ocean Center, there’s always something worth doing. And honestly? Some of our best days as a family happened when the weather pushed us somewhere we wouldn’t have gone otherwise.
So grab a rain jacket, check the radar, and go make some memories. The sun will come back — it always does.
