The improved sections of the park hosts little-league sporting events, but Walnut Creek also has many acres of unimproved wilderness laced with trails that range from beginner to expert. The intermediate and expert sections of the trail are access from beginner level trail which circles the wilderness area. Traditionally, the trail is ridden counter-clockwise to avoid head-on collisions, but there is no hard and fast rules governing direction of travel. There are navigational markers throughout the park which can be used by emergency-services to locate a downed rider.
The trail itself has several short, but significantly rocky and steep climbs of more than 100' in length. There are some ledges and drops off the main trail too if that is your thing. All in all, very little of the trail is perfectly flat - there is always at least some active elevation change as you ride which is why, of the year-round public trails in Central Texas, Walnut Creek is probably one of the best for TMBRA or NORBA race training as it is both fast, has a lot of single-track, hills, but also has some technical sections as well, all of which are 100% ridable for a practiced mountain biker on the proper bicycle.
Parking and Trail Access
Walnut Creek park exists, as one would reckon, along Walnut Creek. The main park entrance is is located off N. Lamar Blvd just south of Parmer Ln. in Austin TX. along the west curb-line. Most bikers park in the pool parking area just up the hill from the entrance and to the left.
