Bring a flashlight or headlamp with extra batteries. The cave is completely dark inside, and having reliable lighting is essential for safe navigation through the lava tube passages.

The lower cave is more challenging with steep climbs and loose volcanic rock. The upper cave is easier and shorter. Choose based on your fitness level and caving experience.

No permit is required for day visits. Groups can be any size, but larger groups should plan ahead as parking is limited. Visit during off-peak hours for better experience.
