Darwin Island is tiny and very, very remote. They first put someone onto the island by helicopter in the 1960s! But all of the dives are actually at Darwin’s Arch, in an area about 200 metres long. Darwin's Arch is a natural rock arch located less than a kilometre from the southeast corner of Darwin Island, Galapagos, Ecuador. The arch sits atop a wide, flat rock platform. This is the only site we dived at Darwin Island and it's rated as the best dive site in the Galapagos and by many as one of the best dive sites in the world. Strong currents from the south split as they hit the plateau and wrap around the dive site. Minor variations in the direction of the currents cause a big difference in where they split and thus where the dive guides will start the dives.
