The world's longest known lava tube at 42.5 miles — a completely raw and unforgettable underground experience. The 2-hour Lava Falls tour is perfect for kids 8 and up. Led by Harry Shick who has studied this cave for decades. Very different from Thurston Lava Tube — completely unlit and natural. Bring good hiking shoes, a headlamp, and cash. Group size limited to 6 so book ahead. Not suitable for young children due to ladders and uneven terrain.

ATV tours through rainforest and lava landscapes. Young kids (3–15) ride along with an adult — check age and weight requirements before booking. Great for families who want an off-road adventure.
