Located in the southwestern part of Easter Island, the Ranokau Crater is a huge dormant volcano. It is nearly 3 kilometers in diameter and its interior forms a deep blue lake with spectacular views. The crater has a steep rim and is surrounded by a unique flora. It is not only a natural wonder but also an important part of Easter Island's culture, with the ruins of the village of Olongo found nearby revealing the history and social structure of the island. Lanokau Crater is an excellent place to explore the natural and cultural heritage.
