The Greenbelt is a 7.25-mile (11.67 km) stretch of public land spanning from Zilker Park west to the Lost Creek neighborhood.

Located in Austin, Texas, the Barton Creek Greenbelt has a humid subtropical climate characterized by hot summers and mild winters.

The Greenbelt receives 30 to 35 inches (760 to 890 mm) of rain annually, with the majority of the precipitation coming in the spring and the second highest in the fall.

During years of heavy rainfall the water level of the creek rises high enough to allow swimming, cliff diving, kayaking, and tubing.

However, John Hartman orchestrated a meeting with the Parks and Recreation board to get that portion opened, prevailing after lining up at least 10 major neighborhood groups to argue against the special deal.

Other nonprofits, including Greenbelt Guardians, Central Texas Mountaineers, and the Austin Ridgeriders also play a big role in volunteer maintenance.
