On the bucket list of many, the Galapagos Islands combine exceptional wildlife with jaw-dropping scenery. The UNESCO World Heritage Site is located approximately 1,000km off the coast of Equador, and contains 21 islands within its archipelago. The islands are surrounded by a marine reserve, and as a result the area is a ripe underwater wonderland full of varying marine life. Cruises to this area tend to be of the expedition variety, with a small number of cruise lines offering Galapagos island hopper itineraries.
