This is very technical singletrack. There are two trails, one for beginners and one for more advanced riders. I don't know of anyone who has ridden the advanced trail w/out dabbing. The trail is only 10 miles (out & back) but it will work you. There's a lot of short, steep ups and downs, and not a lot of high-speed sections. If you can ride this trail, you can ride just about anywhere! Very hot in the summer, with no water available on the trail (although you're usually a stones throw away from Hogan Reservoir). SCAAB (Stockton Cyclists Are Always Bleeding- email@example.com) is continuing to work on this trail to make it longer. Please wear your helmet!
How to get there:
Take Highway 26 out of Stockton or 12 out of Lodi to Valley Springs. At the 4-way stop in Valley Springs, continue on 12/26 to Lime Creek/St. Petersburg. Turn right, then turn right again on St. Petersburg. Follow this for approx. 1 1/2 miles to Acorn East Campground. Park in the Day Use area. Follow the bike signs across Oak Knoll campground to the trail head. The signs will not tell you the beginning of the advanced trail (yet), so keep a lookout to your left for singletrack. If you find yourself on a wide, easy trail, (The Rim Trail) you missed the advanced singletrack and will need to double back.
