Seven distinct trails of varying difficulty, 1,150 acres of coastal mountain woods and panoramic views of the Pacific ocean make San Pedro Valley County Park ample relief from the suburbs and city for any outdoor enthusiast. Three freshwater creeks span the park, providing both cool places for hikers to rest and one of the few spawning grounds for migratory steelhead trout left in Northern California. The south fork of the San Pedro Creek, one of those that cut the valley, is used as as a seasonal water source by Pacificans and was previously a trout farm. The dense flora of the San Pedro Valley, which was once used by Spanish missionaries as an agriculture hub because they could not grow the food they needed or graze their cattle on the sand dunes of eastern San Francisco, offersamateuror serious botanists a trip. Common plants such as Creek dogwood, watercress and species of fern populate the area while, during the springtime, wildflowers crowd sunny meadows. Like most parks in this area, there are no dogs, ground fires (barbecuesonly), or smoking permitted.
