Barton Creek Greenbelt (BCGB) is my home trail system. It is probably the best trail for visitors from out of town especially those who stay at Downtown Austin. This trail system has several access points and this video will take you from the iconic MoPac Bike & Pedestrian Bridge to the Austin's most-loved park - Zilker Park. There're many interesting places along the trail including multiple rock climbing/bouldering spots (e.g. Seismic Wall and Gus Fruh), The Flats (wide open limestone riverbed), Barton Springs/Pool, and many small natural pools.
