Start at the Stanislaus US Forest Service parking lot. You can either go down Lumsden road and back up, or you can make it into a loop. Ride by the Pines campground sign and then take your first left onto dirt forest service roads off of Highway 120. This forest service dirt road will bring you along the ridge of the Tuolumne canyon which will give you great views into Yosemite! <br><br>Continue on the forest service road until you get to the back of the Buck Meadows Restaurant (stop for a beer and lunch if you're hungry :)) From here, you'll start heading down into the canyon on semi-rocky doubletrack trails. The downhill lasts for 3-4 miles and will put you at the bottom of the canyon next to the river and the Lumsden campground. <br><br>You can ride another 3 miles to get to the Lumsden bridge and see a great view of the waterfall (shown on this gpx track) or you can head up the 5 mile Lumsden road to get back to the Lumsden trailhead. From here, get back on Feretti road for 20 feet and take the forest service dirt road that will bring you back to the US Forest Service Office. You'll be required to ride on Highway 120 for a quarter mile.

Panorama from lumsden road riding up. Here the grade up the canyon is very mellow but it gets steeper above. You can slightly make out the road going up the canyon in the photo.
