The quickest access into the Mitchell Hill trail system is by way of Horse Trail Road. This road is located on the east side of the West Valley Road; about ¾ of a mile south of the entrance to the English Camp Unit of the San Juan Islands National Park. It is about the same distance north from the junction of Mitchell Bay Road and the West Valley Road. Park at the end of this short road but do not block gates. Be careful parking, there is very little room and deep ruts can trap even larger vehicles.
