It is a thrill to visit Easter Island and see the famous moai that were carved from volcanic rock. While on the island, also called Rapa Nui, you can observe many moai standing on their altars. Rarer though are the moai that still have their hats, or topknots attached. These hats were made from red scoria volcanic rock and are more fragile than the rock used to carve the bodies. When adorned with their topknots, these well-dressed moai create memorable impressions.
