Site details

The most popular shore dive in Monterey, located beside the 1,700-foot Coast Guard breakwater built in the 1930s. A gently sloping sandy beach gives one of the most protected entries in the area, leading to a boulder wall encrusted with strawberry anemones, sponges, tunicates and nudibranchs, with a resident sea lion colony at the breakwater tip. Heavily used by training classes; weekend visibility suffers and parking fills early.
