» Redwoodhikes Trail Map: Great map showing many parks like Purisima Creek, Huddart, Wunderlich, El Corte De Madera, Foothills, Hidden Villa and Rancho San Antonio. Trail maps for individual parks are available online for free. However, the RedwoodHikes map shows the big picture and is helpful for planning hikes that go through multiple parks.

A good trail map is necessary to do this hike: there are too many trails and too many unmarked junctions. In brief, the route goes along the following trails: Toyon Trail all the way to a lake → Spanish Trail → Sunrise Trail → Buck Meadow Trail → Blue Oak Trail → Deer Path Trail → Arroyo Trail → Coalmine Trail → Old Spanish Trail. This is an extension of a shorter route described at RedwoodHikes.
