About this place
A long lava tube once used for shelter and cultivation—cool geology minutes from major sites.
Ana Te Pahu (“cave of the drum”) illustrates how Rapa Nui farmers used volcanic tubes as natural greenhouses for bananas and other crops, moderating temperature and humidity. Today wooden walkways and low lighting protect both visitors and roots; flash photography is discouraged because it disturbs bats and nesting insects. Guides often demonstrate acoustics—sound carries oddly along the tube’s wet walls.
Inside the cave
Ceiling drips are common—waterproof camera bags beat open backpacks. Some passages require ducking; travellers with claustrophobia should ask about route length before entering.
