The Barton Creek Greenbelt extends 7.5 miles one way from Ziker Memorial Park, near the southeastern terminus of the Lady Bird Lake Trail. At the start, it’s more parkland along the creek. But along the way there are numerous offshoots for running/hiking, including some more rugged trails that lead to cliffs, rock climbing, and some swimming holes. The last section is the famous “Hill of Life”, which is a 300m climb in 0.3 miles. This is fairly technical, challenging trail running in parts. We’ve mapped out the entire 7.5 mile trail one-way. A good place to turn around is at the 4-mile mark at Rt. 360, where the trail gets more rugged. Apparently the Taco Deli on Spyglass is the place to fuel up.
