Natural Bridges State Marine Reserve

Natural Bridges State Marine Reserve is a protected ocean area along the northern coast of Santa Cruz, California, extending roughly 200 feet from shore. It contains sandy beaches, rocky intertidal zones, tidal marshes, and surfgrass beds that support a variety of marine life.

This marine reserve was established in September 2007 as part of a major initiative to protect ocean ecosystems along the California coast. The creation reflected a broader effort to safeguard marine habitats across the state.

The reserve sits beside a state beach where thousands of monarch butterflies gather each winter during their migration cycle. This natural gathering draws visitors who come to witness these butterflies in their seasonal habitat.

The area welcomes kayaking, diving, and snorkeling while prohibiting fishing and collection of marine organisms. Visitors can enjoy water activities while understanding that the reserve prioritizes protection of the ocean environment.

Seals and sea otters inhabit the waters here, often visible to kayakers and divers exploring the reserve. These marine mammals signal a healthy ocean ecosystem and add a special element to any visit.
