A volcanic archipelago some 600 miles off the coast of Ecuador, the Galapagos Islands are an unspoiled paradise for animal and nature lovers. The vast majority of the land and surrounding waters is part of the Galapagos National Park, and a lot of the wildlife can't be seen anywhere else in the world (the whole thing is a UNESCO World Heritage Site). Most cruise itineraries are seven to 10 nights, plus a one- to two-night hotel stay on either end on the mainland of Ecuador in either Guayaquil or Quito to accommodate flight connections.
