Tortuga Island is a dive site located southeast of Isabela Island in the Galápagos, centred on a high but small island that offers several distinct dive sites within its waters, reached roughly 30 minutes from a ship's anchorage.
The submarine topography varies around the island, featuring vertical walls and shallow slopes depending on the area chosen, with a maximum depth of 16 metres and a rocky bottom throughout. The range of terrain means the site can be dived at different levels of challenge, making it accessible to beginners and advanced divers alike, though some previous experience is still recommended.
The site holds an impressive range of marine life: mantas, stingrays, eagle rays, hammerheads, white-tipped reef sharks, sea turtles, tuna, and barracuda are regularly encountered alongside reef fish such as king angelfish, yellowtail surgeonfish, barberfish, blue chin parrotfish, bumphead parrotfish, Galápagos groupers, Galápagos sheephead, harlequin wrasse, and grey grunts. Lobsters and octopus also appear, and large gorgonians, corals, and sponges are visible across the site. With luck, orcas and mola molas may also be spotted.
Conditions vary considerably depending on which side of the island is being dived and prevailing winds. Currents can range from strong to wild by location, so divers should be prepared for variable surface conditions. Visibility is generally good, running from around 12 to 20 metres. Water temperature sits between 22–24 °C from November to May, dropping to 18–20 °C from May to November.
