Lonely Planet review for Lava Tubes
From the village of Bellavista, 7km north of Puerto Ayora by road, one can turn east on a road leading about 2km to the lava tubes. These underground tunnels are more than a kilometer in length and were formed by the solidifying of the outside skin of a molten-lava flow. When the lava flow ceased, the molten lava inside the flow kept going, emptying out of the solidified skin and thus leaving tunnels. Because they are on private property, the tunnels can be visited without an official guide. The owners of the land provide information, guides and flashlights ($1). Tours to the lava tubes are offered in Puerto Ayora.
