Lady Bird Lake Hike & Bike Trail · Barton Springs

The Colorado River through Austin is the heart of the Texas capital's outdoor culture. Lady Bird Lake (Town Lake) offers flatwater paddling through the downtown skyline, while upstream stretches deliver gentle Class I–II riffles through Hill Country limestone. Barton Springs, fed by the Edwards Aquifer at 68 degrees year-round, anchors one of America's great urban swimming and paddling corridors.

Data Quality

River conditions are community-verified. CFS ranges, difficulty ratings, and trip sections may not reflect every flow level or seasonal change. Always check current conditions, scout unfamiliar rapids, and paddle within your skill level. If you spot an error, use the Improve This River button at the top of the page — your local knowledge is what makes this atlas accurate.
