Sea lions at Cape Marshall
Playful sea lions at Cape Marshall, Isabela Island

Cape Marshall

A near-vertical wall of volcanic rock that plummets to the bottom of the sea, this dive site boasts the big stuff: manta rays, hammerheads, sun fish (Mola mola), and sometimes huge schools of the endemic salema.


Not only is the topogrpahy of this site distinct and fascinating, but so is the marine life! The “usual” sea turtles and sea lions swim along with you and the Chevron barracuda, yellow fin tuna, marbled rays, mobula rays, snappers, and more!
