World's mysterious islands

Easter Island
One of the world's most famous archaeological sites, Easter Island is a small, hilly, now treeless island of volcanic origin some 2200 miles off the coast of Chile. Easter Island's mysterious 'Moai', giant head statues carved out of volcanic rock, draws tourists to the world's most remote inhabited island. The people of Easter Island called themselves the Rapa Nui. Where did they come from and why did they disappear? Science has put to rest some of the more bizarre theories, but questions remain.
