Fodor's Expert Review Rano Kau

This huge volcano on the southern tip of the island affords wonderful views of Hanga Roa. The crater, which measures a mile across, holds a lake nearly covered over by reeds. The opposite side of the crater has crumbled a bit, revealing a crescent of the deep blue ocean beyond. Entering the crater is forbidden, except in signposted areas. It is protected, and the ground is unstable.
