The Colorado River flows through Travis County, impounded into Lake Travis and Lake Austin, key recreation anchors for the region. The Balcones Escarpment marks the transition from the limestone Hill Country in the west to the Blackland Prairie in the east. Barton Creek and its tributaries carve spring-fed swimming holes and nature preserves within the urban fabric.
