Caverna de Dos Ventanas is one of Easter Island's memorable lava-tube visits, known for the two openings that frame the Pacific at the end of the cave. The approach is low and dark, which makes the sudden blue windows feel theatrical rather than merely scenic.
Bring a torch and wear shoes you trust on uneven volcanic rock. The cave is often linked with Ana Kakenga, and it works best as part of a west-coast circuit rather than a rushed checklist stop.
