Ana Te Pahu
Located below the Akivi ahu in an area called Roiho. It is a long tunnel of lava, the biggest one in the island, where people could take shelter from the raids conducted by slave drivers. It is easy to access the tunnel through the collapsed ceiling, and only a flashlight and a pair boots are needed to explore it, since very few parts are flooded. Thanks to several natural skylights, it is easy to find one’s way in the caverns. This lava tube formed by the hardening of a basalt layer during the flow of a lava river is one of the many caverns in the island. It probably solidified less than 10,000 years ago, during the eruption of the Munga Hiva Hiva volcano, the last volcanic manifestation in Rapa Nui. These natural landslides were used as gardens protected from the wind (manavai).
