San Gregorio State Beach is located in San Mateo County, California, south of Half Moon Bay. It features a wide, sandy beach with a protected driftwood-strewn estuary and is backed by steep, grassy bluffs along the coast. The beach is part of the California State Park System and is known for its cleanliness and natural beauty, including a freshwater lagoon behind a sand berm. San Gregorio Creek historically supported coho salmon spawning and is being considered for restocking efforts.
The beach offers a serene environment perfect for nature lovers and those seeking a peaceful escape. It is also celebrated for its role in history, being a spot where Spanish explorer Captain Gaspar de Portolá passed through in 1769.
North of the main beach, there is a nude beach area located on private property, reflecting the diversity of activities and amenities in the area.
