Barranco Cave
Why dive here
With 131+ marine species recorded in the area - including dolphins, humpback whales, seals & sea lions, sea turtles and sperm whales - Barranco Cave offers some of Galápagos Islands's richest cave diving. Water ranges 23-28°C, warmest February, March, April.
Barranco Cave, off San Cristobal, offers a peek into a different side of Galápagos diving. It's not about the big pelagics here, more a deep dive into a geological feature. You’re looking at a cave environment, so expect to navigate some tighter spaces, but nothing overly technical. We usually find nudibranchs, some schooling fish, and lobsters tucked into crevices. Depths range from 23 to 34 metres, making it a good fit for divers comfortable with deeper profiles and overhead environments.
