McKinney Falls State Park

Overview

McKinney Falls State Park is a 726-acre state park on the southeastern edge of Austin where Onion Creek tumbles over exposed limestone shelves, creating scenic upper and lower waterfalls.

Highlights

• Upper and Lower Falls: Two distinct waterfall areas with swimming holes below each cascade.
• Homestead Trail: A 3.1-km loop passing the ruins of Thomas F. McKinney's 1850s homestead.
• Geological Formations: Exposed volcanic ash deposits and Cretaceous limestone visible along trails.

History

The park is named for Thomas F. McKinney, one of Stephen F. Austin's original colonists. His homestead and gristmill ruins from the 1850s are preserved within the park. It became a state park in 1976.
