Santa Monica Mountains National Recreation Area

There are multiple trailheads around the park, so there is not one main entrance. You can begin your visit at the visitor center, located off Mulholland Highway in Calabasas. The Santa Monica Mountains are traversed by the 405 Freeway on the east side; crowned by the 101 Freeway on the north and west side; and Highway 1, the Pacific Coast Highway (PCH), on the southern ocean border.
