At the campground located at the end of the above road, there is a 3 mile doubletrack loop suitable for night riding. Leaving the campground the way you came in there is a bright yellow gate at the trailhead. The trail is a network with many offshoots and intersections. The singletrack leads you to Dixson State Park and the thirteen mile loop has some long boring parts, but there are scenic highlights along the way and even a few technical sections that will leave you smiling. This is an awesome place to camp, and a decent place to ride.
Take Hwy 24 to Hwy 146. Go east on 146 about 10 miles to 145. The intersection of 146 and 145 is an interesting cloverleaf deal. Turn right off of 146 onto the ramp then turn right onto 145 going north, its much easier than it sounds. Go north on 145 about 4 miles and turn right into Lake Glendale Rec Area. Continue to the right at the fork in the road and follow it all the way back until you run out of road, about a mile.
