Darwin Island is considered by many experienced divers as the very best dive site in the world, the Arch at Darwin Island (actually several dive sites depending on where you enter, currents, etc.) lives up to its reputation. Warmer by a few degrees than the central islands, in one single dive you can find schooling hammerhead sharks, Galapagos sharks, large pods of dolphins, thick schools of skipjack and yellow fin tuna, big eye jacks, mobula rays, and silky sharks. From June to November, it is not uncommon to encounter whale sharks in multiple numbers on one single dive. The presence of occasional tiger sharks, black and blue marlin, and killer whales add to this amazing diving experience. If you still have time to look for smaller stuff, you’ll find octopus, flounders, and an enormous variety and abundance of tropical fish. Darwin Island is the biggest jewel on the Galapagos Crown.
