Isle du Bois State Park

Trail Description

Isle du Bois MTB Trail is a stacked loop trail system located within the Isle du Bois Unit of Ray Roberts State Park. This trail system is one of the most challenging trails in the DFW area, featuring very rocky terrain, including numerous rock gardens, rocky climbs, gnarly descents, and even one section with several yards of loose sand. You’ll need a Texas State Parks annual pass to enter, or pay $7 per person at the main gate.

The most difficult sections of the trail are located on Loop D, which in itself is highly challenging. These two, optional “expert” sections may be bypassed. To ride the entire trail—Loops A through E—take every left intersection except for the two Loop D bypasses.

The trail is marked throughout with emergency location posts—each has a red/white reflector and a number. The numbers do not correspond to mileage. If you have an emergency, tell the park rangers or emergency responders the last number you saw and they’ll be able to locate you more quickly.

It’s highly recommended you do not ride this trail alone. Most riders do not receive adequate cell service.

The trailhead is located near the very end of the main park road. As you come over the last hill on the road, you’ll see the lake ahead. Park in the parking lot to your right before you get to the larger parking lot straight ahead (where the boat ramp is located). The trailhead is located on the eastern edge of the parking lot.

See map below for details on the individual loops. You’ll also see the fire road which comes near Loop C/Loop D junction. At the turnaround for Loop C, follow the paved trail east for a few yards until you find the fire road heading north. You can use the fire road to skip Loop D and move directly to Loop E. There is also a paved loop around Loops A through C which you can also use to find your way back to the trailhead if necessary.
