It is a 7.8-mile trail for hiking and bicycling. Several swimming holes dot the trail. Rock climbers also practice on the limestone cliffs. The trail is rocky and semi-primitive and cuts through scenic wildflowers, trees, limestone cliffs, caves, meadows, swimming holes and waterfalls. The trail varies from narrow ledges to wide walkways.
Wildlife is abundant in the park.
Hiking in the Greenbelt will really give you the feeling of being far away in the wilderness, not in the middle of the city, which it really is. The trail extends from Zilker Park to Lost Creek, with a trailhead at Zilker Park just west of the pool. The Loop 360 and Gus Fruh sections are wheelchair-accessible. Dogs are permitted on leash only. A new trail is being built that will connect Southwest Parkway with the Greenbelt at the MoPac Bridge.
