It is located in the Los Osos Valley between San Luis Obispo and Baywood Park-Los Osos, just outside the town of Los Osos. It is also the only place the critically endangered Splitting Yarn or Iron Maiden's Hair lichen Sulcaria isidiifera can be found. The 85-acre (34 ha) park was established in 1972.
