Loch Raven Reservoir: Glen Ellen–Seminary Road Professional Guide
Detailed Trail Description from our Guidebook
"Follow the natural contours of the southeastern edge of Loch Raven Reservoir before ascending the hills above to come back through upland forest. At the trailhead, you’ll see a bulletin board explaining which trails are open to mountain bikes and which aren’t. Be aware: these are largely ignored. According to the sign, bikes are allowed only on the wide fire road that begins to the right of where you stand. Even though you are heading left at 200 feet on the narrower dirt path, expect a few bicyclists.
Hundreds of offshoots lead in both directions from the trail; these singletrack bike cuts lead to some nice scenery, but they cause severe erosion. Besides, staying on the path yields some fantastic views. Cross over a small stream at 0.7 miles and then head slightly to the right into a grove of pine trees. This is part of the fire road, and it is accordingly wide—only a thin strip made by tire tracks cuts a path in the middle."
