Singletrack that offers expansive views of West Marin and San Francisco. You can either start the trail near Four Corners in Mill Valley along Panaramic Highway and descend to Muir Woods or vice versa. Note: This trail has been converted from a fireroad to a singletrack. Great single track that sees a lot of mixed usage. Mostly mountain bikers, some hikers, and a few horse riders as well since the trail ends at a horse stable in Muir Beach. Nothing but smiles and people enjoying the beautiful scenery. Descending from Four Corners, it begins as a smooth single track and slowly becomes slightly more rocky. Towards the end of the trail, there are many tight switch-backs, water bars (read: pay attention if you're on a bike). Muir Beach is also a short .5 from there and the Zen Gardens are right around the corner. Miwok Trail, Middle Green Gulch, and the Coastal Trail are all easily found from this trail.
