Martins Beach
Martins Beach extends along the central California coast, about 40 kilometers south of San Francisco, in San Mateo County. This stretch of the Pacific coastline is characterized by ochre sandstone cliffs overlooking a narrow coastal strip, typical of this region where the Sierra Nevada plunges directly into the ocean. The shore, exposed to North Atlantic swells that cross the Pacific, offers a wild and undeveloped ambiance, contrasting sharply with the more accessible beaches located further north. The beach itself presents as a relatively isolated cove, framed by rock formations that limit its lateral extent. In the immediate vicinity, Tunitas Beach is 2.3 kilometers to the south, while Whale Bone Beach extends 3.5 kilometers away, offering variations of the same preserved coastal environment. Access remains restricted and requires some determination: the path leading to it crosses private property, which explains the sparsely populated nature of the place. The waves here are often powerful, attracting surfers and marine wildlife observers, particularly seals and whales during migration periods. No facilities are reported on site. The beach does not have the Blue Flag label and is not supervised. Access is not arranged for people with reduced mobility. This lack of infrastructure is part of the site's charm, preserving its wild character and reserving it for visitors who accept a certain rusticity.
About this spot
Martins Beach derives its name from the pioneering families who settled in this region in the 19th century, when central California was still largely unexplored. The coastline here, formed by the erosion of ancient geological formations, remains one of the few stretches of the San Mateo coast to have escaped massive urbanization. For decades, the beach remained freely accessible until the 2000s, when a landowner closed public access, creating a local controversy that persists. Recurring land disputes have turned this place into a symbol of the tension between private property rights and public access to Californian coasts.
