Spending time underwater, whether snorkeling or diving, is one of the top things to do in the Galapagos, one of the world’s best destinations for wildlife lovers, including those who want to see marine life. You might find yourself swimming right next to a marine iguana, an adorable Galapagos penguin, or a curious sea turtle. There is a wide range of colorful reef fish too. The visibility is at its best from December through May, which is the warmer, wetter season, but you can still see plenty between June and November as the Humboldt current brings rich nutrients to the area, which provides a feast not only for marine life but the archipelago’s many birds. Some of the top spots include Tortuga Bay on Santa Cruz Island and Kicker Rock on San Cristobal, where stingrays, eagle rays, eels, and whitetip sharks often make an appearance.
