McKinney Falls State Park
Creek · Texas
About this swimming hole
Onion Creek spills over limestone ledges into two beloved swim pools, the Upper and Lower Falls, minutes from downtown Austin. The pools are deep enough for jumping and shaded by old-growth pecan and cypress. Swimming closes when bacteria levels rise after rain, so check the park's alerts.
