This ragged semicircle of rocks, poking up out of the ocean a few hundred meters from Punta Cormorant, is one of the most outstanding marine sites in all of the Galápagos. A strong current sweeps snorkelers briskly past thousands of bright tropical fish, a small coral formation, sea lions, marine turtles and the occasional shark. A panga ride around the semisubmerged volcanic cone will give views of red-billed tropicbirds, pelicans, herons and lava gulls nesting on the rocks.
