Stillwater Cove Regional Park is a regional park north of Jenner, California, U.S.A. that is maintained by the Sonoma County Regional Parks Department. It is located near the mouth of Stockhoff Creek. Access is by means of State Route 1. It was one of the filming locations for 20th Century Fox's 1947 fantasy film, "The Ghost and Mrs. Muir".
Stillwater Cove Regional Park is accessed by a gravel road
It is neither because it doesn't tell us what type of road State Route 1 is. The system may be confused because it thinks I'm saying the access is a gravel road and that I'm ignoring state route 1
