Pike County Gulch is a coastal valley in Marin County, California, United States, which is associated with a small stream. It is located between Wilkins Gulch (to the northwest) and Audubon Canyon (to the southeast).
The stream descends the western slope of the Bolinas Ridge, crosses State Route 1 about north of Stinson Beach, California, and drains into the northern tip of Bolinas Lagoon.TopoQuest map, USGS, retrieved July 5, 2008
