Cabo Marshall
Why dive here

Cabo Marshall, way out west from San Cristobal, is the spot for giant mantas in the Galápagos. We've had days there where a half-dozen swept past, silent and huge, and other dives where we were just a bit too early or too late. Even on those quieter days, though, you’re still surrounded by white tips, maybe some hammerheads cruising deeper, and playful sea lions zipping around. It’s a site for those who appreciate the big pelagics and understand that nature runs on its own schedule. We’d suggest focusing on the thermocline breaks; that’s often where the action is.
