The hiking trails in Marin County,California, are numerous and have some of the best views one could ask for. To name a few: Bear Valley trail from Point Reyes National Seashore Headquarters to Arch Rock on the ocean, most any trail on Mt Tam and any of the Marin Municipal Water Company trails. The pictures below are on the Water Company property near Fairfax.
