James V. Fitzgerald Marine Reserve

The Fitzgerald Marine Reserve is part of the San Mateo County Parks system. Within the reserve are great communities of marine life, including sea stars, anemones, sponges, and crabs. Most of the marine life can be seen in the inter-tidal zone pools. The best time to visit the tide pools is during zero or negative low tides.


A network of trails leads around the reserve. One of the most popular trails follows the bluff, offering views of the Pacific Ocean. An observation point is located near the northern end.
The California Coastal Trail extends through the park. It is an accessible multi-use trail open to walkers, equestrians, and cyclists. The Coastal Trail continues south, connecting with Pillar Point Bluff trails and the Half Moon Bay Coastal Trail.

Ocean Safety

California State Parks and Recreation cautions that "large surf, cold water temperatures, backwash, sudden drop-offs, pounding shorebreak, and dangerous rip currents can turn what seem like safe activities such as playing near the surf line, wading, or climbing on rock outcroppings, deadly."
