Galapagos

Famous for their incredibly fearless and unique wildlife, the Galapagos Islands are best experienced on a cruise. You can swim with sea lions, float eye-to-eye with a penguin, stand next to a blue-footed booby feeding its young, watch a giant tortoise lumbering through a cactus forest, and try to dodge the iguanas scurrying over the lava. The wildlife is truly phenomenal and the scenery, which is barren and volcanic, is hauntingly beautiful.
