About 35 miles of multi-use double track, old road. Requires a free permit available at the building. A map is also available at the building. Trails are well marked with signs. Although it's a network, many trails are out-and-backs to the lake. Not very hard, but there are some soft gravel spots and rocky areas. Trails farther away from trailhead are less used, but rideable. Don't think the Boundary Trail actually exists - it just follows the fence along the boundary. Beginners can do most of it, but advanced riders can really fly. Scenic overlooks and wildlife are present. Access to McGee Creek Reservoir is available from many trails.
Located 16 miles east of Atoka, then 3 miles north of Hwy 3.
