At the geologic center of the archipelago, Rabida presents a different "look" from the other islands, with its reddish beach and cliffs, and steep, sloping volcanic cinder-cones. A noisy colony of sea lions lives on the beach, and a short trail inland is a good place to observe land birds, including finches, doves, yellow warblers and mockingbirds. Hidden behind a narrow strip of green saltbush is a briny lagoon where flamingoes are often seen, sometimes nesting. Snorkeling along the rocks at the east end of the beach reveals many reef fish common to these waters.
