Inside the cone of Rano Raraku volcano is a lake fringed by totoro reeds. Each year, this is the scene of a traditional triathlon in which Rapa Nui men compete by paddling rafts of totoro reeds, swimming, and running with heavy bunches of bananas up to the summit of the crater. The far side of the crater, you can just make out some of the carved stone figures or moais for which Easter Island is famous. The vast majority of Easter Island's 800+ moais were chiselled out of the volanic tuff on the side of Rano Raraku between 700-1500AD.
