About this swimming hole
A historic Blanco River dam creates a deep, still pool that San Marcos locals have swum for a century. The old dance hall foundation and pecan trees give it a time-capsule feel missing from the bigger parks. Check current access status before going, as the county park has had intermittent closures.
