Five Mile Dam Park is a public recreational facility situated along the Blanco River in Hays County. The park features a low-water dam that creates a popular swimming hole during warmer months. Beyond the water, the site provides multiple soccer fields utilized for local league play and youth sports. A network of unpaved trails winds through the wooded areas surrounding the river banks. Picnic areas are available for public use throughout the grounds. The park serves as a community hub for outdoor fitness and river-based recreation near the San Marcos area. Access to the river requires navigating natural terrain along the shoreline.
The elevated bank overlooking the low-water dam provides the best vantage point for capturing the river flow.
Bring water shoes to navigate the rocky riverbed and slippery river rocks safely.
Check local Hays County weather alerts before visiting, as heavy rain can lead to flash flooding and park closures.
Apply insect repellent, as the riverside vegetation attracts mosquitoes during humid months.
Do not attempt to swim near the concrete dam structure itself, as the undertow and current can be hazardous.
The park may close periodically during or after significant rainfall due to potential river flooding.
Carry out all trash to keep the river ecosystem clean; observe leash laws for all pets.
