Agate Beach County Park, located in Bolinas, California, is a hidden gem along the Pacific coastline. It offers nearly two miles of stunning shoreline, featuring a mix of sandy and rocky areas, with Duxbury Reef extending out from Duxbury Point. The beach is renowned for its vast tide pools, which are exposed at low tide, providing an excellent opportunity to explore marine life. Visitors can enjoy breathtaking views of the Pacific Ocean and, on clear days, see all the way to the Farallon Islands. The area is part of the Duxbury Reef State Marine Conservation Area, emphasizing the importance of preserving marine life.
The park's unique geology, with shale reefs and sandstone cliffs, adds to its natural beauty. Agate Beach gets its name from the semi-precious agate stones found along the shore, which form in the volcanic rocks of the area. The beach is accessible via a scenic drive through Marin County, with parking available at the end of Elm Road.
Agate Beach is a popular spot for nature lovers and outdoor enthusiasts, offering activities like tidepooling, wildlife watching, and fishing. It is also dog-friendly, allowing leashed dogs. However, camping is not permitted, and the park is open from sunrise to sunset.
