Hazard Canyon Reef

Book Your Stay

Hazard Canyon Reef, located within Montaña de Oro State Park, is a gorgeous beach with tide pools and scenic views. The area is accesible via a one-mile hike on Dune Trail, which includes wooden stairs and a boardwalk to get you safely into the mouth of the canyon. Go through the 4-way junction, then between the dunes, and the trail will end at a rocky shore. Explore the tide pools for hermit crabs, sea stars, sand dollars and anemones.

The trail is named, not for the terrain, but for a prior landowner who planted the eucalyptus trees in hopes of selling them as lumber.
