Not a lot of climbing, but good technical challenges
700 acres offers some great technically challenging singletrack. Roots, baby-head rocks, hills and jumps await the skilled rider. The North end, though often ridden is posted with "No Trespassing" signs. The South end (lower section) offers more trails and better riding anyway so be a good little IMBA rider and stay on the open trails. In addition to the on-trail obstacles, low hanging branches and exposed cliffs also force you to keep alert
How to get there:
In San Antonio, take I-410 South to Exit #39. Turn right onto WW White and then left at the stop sign onto Military Drive. Follow Military Drive West for 2 miles and then turn right onto Alsbrook Drive. There is parking along the side of the road. Hop on your bike and ride further down Military Drive a couple hundred yards and under the bridge to the trail.
