For children, the Big Island is a living science lesson. They can walk through a tunnel made by lava, watch steam rise from a volcano, see turtles asleep on black sand and peer at the stars through telescopes on a mountain higher than the clouds. It suits curious, adventurous kids best, and rewards a little planning.
The best things to do on the Big Island with kids
1. Walk through the Nāhuku lava tube
A short loop through a tunnel formed by flowing lava in Hawaiʻi Volcanoes National Park.
2. Junior Ranger at the national park
Children can earn a badge at Hawaiʻi Volcanoes by completing activities.
3. Look into Kīlauea's caldera
Steaming vents and the vast crater fascinate children; follow closures, as some areas have been closed since October 2026.
4. Turtles at Punaluʻu
Green sea turtles often rest on the black sand. Keep 10 feet away.
5. Snorkel at Kahaluʻu Beach Park
A shallow, sheltered bay near Keauhou with turtles and fish.
6. Calm Kohala beaches
ʻAnaehoʻomalu Bay at Waikoloa and Kaunaʻoa are often calm and sandy.
7. Manta rays at night
For confident older swimmers; many operators set minimum ages.
8. Stargazing on Mauna Kea
Watch the sunset and stars from near the Maunakea Visitor Information Station at about 9,200 feet, or join a family-friendly stargazing tour; check the station's current programmes and bring warm clothes. Children under 13 should not go to the summit because of the altitude.
9. Puʻuhonua o Hōnaunau
Wooden kiʻi statues, a great wall and stories of the place of refuge.
10. ʻAkaka Falls
A short, paved loop through rainforest to a 442-foot waterfall.
11. A farmers' market in Hilo
Exotic fruit tasting for adventurous eaters.
12. A luau
Several resorts in Kona and Kohala host family-friendly luaus.
Kīlauea in October 2026
Kīlauea in October 2026: because of continued inflation and earthquakes at the summit, the National Park Service closed the Halemaʻumaʻu Trail, part of the Byron Ledge Trail and viewing areas on the Keanakākoʻi side. Other parts of Hawaiʻi Volcanoes National Park remain open. Check the USGS and park updates on the day you go.
Family tips
- Two bases cut the driving: Kona or Kohala, plus a night near the volcano.
- Bring layers: it is cool at the volcano and cold on Mauna Kea.
- Watch for vog (volcanic haze) if children have asthma.
- Plan rest days on calm beaches between big outings.
Where to stay with kids
Waikoloa's family resorts and Kona's condos are the easiest bases; Volcano Village has cabins near the park. See where to stay on the Big Island.
A family day near the volcano
Drive to Hawaiʻi Volcanoes National Park in the morning and pick up a Junior Ranger booklet at the visitor centre. Walk the short loop through the Nāhuku lava tube, look out over the caldera from an open viewpoint, and let children feel the warm air from the steam vents. After lunch, drive down the Chain of Craters Road to see where lava met the sea, then stop at Punaluʻu on the way back to watch turtles sleeping on the black sand. It is a day of geology children can touch.
