This public marina operated by San Mateo County is a great place to spend an afternoon even if you don't have a boat. The breakwater is a favorite of walkers, and has great views of San Francisco and Mount Diablo. It's surrounded by eucalyptus trees, jogging and bike trails and picnic areas and is also home to the members-only Coyote Point Yacht Club. The entrance is through the Coyote Park Recreation Area off Highway 101 at Peninsula Avenue, near the Belmont city line. Admission to the recreation area is $5 per car, with discounts for senior citizens.
