Why dive here
With 131+ marine species recorded in the area - including dolphins, humpback whales, seals & sea lions, sea turtles and sperm whales - Cousin's Rock offers some of Galápagos Islands's richest diving. Water ranges 23-28°C, warmest February, March, April.
Cousin's Rock is a reliable spot, often a stop on Galápagos liveaboards, sitting off Santiago's east coast. It's really just a triangular rock poking about ten metres out of the water, but what it lacks in grand topography it makes up for in density. We've spent dives here just hovering, watching a parade of mobula rays glide by in the blue, while a Galápagos shark might cruise past the reef edge. The shallows are where we usually find the best action, with sea lions often zipping around, playful and curious. It’s a good choice for divers who appreciate a mix of pelagic encounters and close-up reef critters.
