OP Schnabel has a variety of trails, from flat smooth trails to downhills, climbs, shaded forest and even jumps.
There is a large BMX area with 4-foot high dirt jumps, some even have obstacles like old refrigerators in the middle of the jump. The park is located along a river and crosses over water in several areas. Trails can be rocky in areas and muddy after a rain.
Location: San Antonio, TX
Directions: Take I-35 south to 1604. Take 1604 west (right) down to Bandera Road. Take Bandera east to the entrance of the park. If I remember correctly, there is a huge "Grass" billboard right at the entrance.

Length: 10-12 miles
Trails: Well-cut and well maintained trails. There was a lot of debris along the river paths but everything was rideable. More dirt than rocks, lots of jumps and other diversions.

Post Ride Beer: Tecate. You're in San Antonio, so you can throw a stone and hit 20 great Tex Mex restaurants. Tecate matches the unpretentious OP trails.
