About this site
North West Harbor sits at the northern end of San Clemente Island, one of the more remote of California's Channel Islands, off the Southern California coast southwest of San Diego. The island falls under U.S. Navy control, and access to its surrounding waters is typically limited to boat trips arranged around that use.
