First let me say that it is easy to get lost here so plan enough time to find your way back out. The trails consist of a lot of sand, loose dirt and shale. Motorcycles share these trails so keep an eye and ear out for them. The trails aren't overly technical but there are plenty climbs to give you a good challenge. The fire roads are fast and furious. Flats are common due to the omnipresent cactus, so come prepared.
How to get there:
From San Antonio, take I-35 North to the Pat Booker Road exit. Follow Pat Booker for about 2 miles to Coronado Road. Turn left onto Coronado and go North to the stop sign. The trail is right across the road from here.
