The most iconic hike on Oahu and probably all of Hawaii. The 1.6-mile round trip trail climbs inside the crater of this famous volcanic tuff cone to the summit for panoramic views of Waikiki, the Pacific Ocean, and the Koolau Mountains. Kids love the tunnel, bunker, and steep staircase near the top that add adventure to the climb. The trail is paved but steep in sections. Reservations are required and the earlier you go the better to beat the heat and crowds.

Haleakala National Park Sunrise

Watching the sunrise from the 10023-foot summit of Haleakala volcano is one of the most extraordinary experiences in Hawaii. The crater landscape looks like Mars and the sunrise above the clouds is genuinely life-changing. Kids are awed by the alien-looking terrain and the cinder cones inside the massive crater. It is very cold at the summit (often below freezing at dawn) so bundle up. Sunrise reservations are required and sell out months in advance. Short rim trails at the summit are accessible for families.

Hawaii Volcanoes National Park

One of the most extraordinary national parks in the country centered around Kilauea, one of the most active volcanoes on Earth. The Crater Rim Drive circles the massive Kilauea caldera with overlooks, steam vents kids can feel, and the Thurston Lava Tube, a tunnel through solidified lava that is a highlight for every child. The Devastation Trail is a paved boardwalk through a surreal volcanic landscape. Chain of Craters Road descends through multiple eruption sites to the coast. Seeing an active volcano up close gives kids a sense of wonder that is hard to match anywhere else.

Kilauea Iki Trail

A 4-mile loop that descends through lush rainforest into a volcanic crater and crosses the hardened lava lake floor. Walking across the crater floor is an otherworldly experience with steam rising from cracks in the rock and the crater walls towering above. Kids can see where the lava lake was hundreds of feet deep during the 1959 eruption. The contrast between the lush forest rim and the barren crater floor is striking. This is widely considered one of the best hikes in Hawaii and gives families a visceral connection to volcanic forces.

Koko Crater Railway Trail

A staircase of 1048 old railway ties straight up the side of Koko Crater to the rim at 1208 feet. This is essentially a giant outdoor stairmaster and kids who are up for the challenge love the sense of accomplishment at the top. The views from the rim are panoramic covering Hanauma Bay, Sandy Beach, and the east side of Oahu. The climb is relentless with no shade so start early and bring lots of water. There is a gap in the ties about two-thirds up where a bridge once stood that requires some scrambling.

Molokini Crater Snorkeling

A boat trip to a partially submerged volcanic crater 3 miles offshore with some of the clearest water and best snorkeling in all of Hawaii. Visibility often exceeds 150 feet and the protected interior of the crescent-shaped crater is calm and teeming with tropical fish. Kids are amazed by the underwater visibility and the sheer number and variety of fish. Most tours include snorkel gear, breakfast, and lunch on board. Morning departures offer the calmest conditions. Sea turtles and sometimes reef sharks are spotted in the deeper areas.

Sliding Sands Trail (Haleakala)

hello@adventurehackers.com (AdventureHackers) — Fri, 10 Apr 2026 00:00:00 +0000

A surreal hike into the crater of Haleakala volcano through a landscape of red, orange, and grey cinder cones that looks like the surface of Mars. The trail starts at the summit visitor center at 10023 feet and descends into the crater on soft volcanic sand. Even hiking the first mile in and back out provides incredible scenery. The full trail is long and the altitude makes exertion harder so start slowly. Silversword plants, found nowhere else on Earth, grow along the trail. This is a genuinely otherworldly experience.
