There are countless stunning views around this loop.

Need to Know

This 26.1 mile loop is suitable for experienced riders only. There are a lot of steeper with loose big rocks and difficult switchbacks on the way.

Bring tons of water. It is NOT a three hour bike ride. Bring extra bike tubes and come prepared for possibly a 6-8 hour bike ride with tiring legs at the end.


From the parking lot, the ride starts out on Lower Sunset Trail. This is a nice ride on high ridge cliff. Riders should be very cautious with several small sized boulders/rocks and cactus plants on the sides.

After Lower Sunset Trail, continue on the Bike Loop. This is a very rocky trail with several technical areas.

Next up is Northern Pass where you'll climb on a gravel trail and then up some very steep and difficult switchbacks with boulders/rocks until you reach the top of the pass.

After a brief connecting segment on Hitt Canyon Loop, you'll come to Sotol Forest. This is a fun singletrack with several obstacles (boulders/rocks) to work with but overall it is very rideable.

After Sotol Forest, get ready for Mundy's Gap East. This is the most difficult climb of the loop. The views from the top are worth it!

Finally, the loop concludes on Mundy's Gap West. The road is wide and grade steep. It is rideable most of the time up and down. Riders should be careful as they near the end of trail which is littered with countless large boulders, and most will want to walk this section to the paved parking area of Tom Mays Park.

Tough ride on single speed at the end. The ride sucks you in, with beautiful flowy terrain the first half, then it gets steeper and looser after that 26.2mi — 3h 52m
