Yet another gorgeous and manageable hike here in Marin County is the loop up and around the ridge of Gerbode Valley, on Miwok and Bobcat Trails. Gerbode Valley is tucked between Tennessee Valley to the north and Rodeo Valley to the south, all part of the Golden Gate National Recreation Area.
Parking at a small lot off of Bunker Road, you take Miwok Trail to the northeast. You continue up at a fairly steady incline all the way up the hills on the west side of Gerbode Valley until you reach the summit, right about where the FAA tower is located. There are marvelous panoramic views from the top, with views of Mill Valley, Tiburon, Belvedere, Angel Island, San Francisco, and the top of the Golden Gate Bridge.
From the FAA tower, you walk along a fairly level trail until you reach the Bobcat Trail, which begins the descent back down the other (east) side of Gerbode Valley. The whole loop is a little over five miles and takes about three hours at an easy pace, with stops for photography.
