The San Antonio River Authority (River Authority) operates and manages over ten parks and trail systems, including close to sixty miles of paddling trails along the San Antonio River in Bexar, Wilson, Karnes, and Goliad counties. These public parks and trail systems are filled with abundant wildlife, native grasses, wildflowers, and trees. Not only do these natural spaces provide enjoyment for the public, but they also help protect the habitats vital to the health of the River. We invite you to join River Authority staff on the upcoming Spring Nature Walk series and discover the beauty of the San Antonio River Watershed!

Remember: There are and will continue to be risks associated with recreating in the outdoors. Before heading out, check the Current Conditions & Closures for trail closures and information on flow and bacteria conditions updated every Friday.

Upcoming Nature Walks

In preparation for the 2023 City Nature Challenge (April 28-May 1) the River Authority and the San Antonio River Foundation (River Foundation) are organizing immersive nature walks to help the community discover the unique flora and fauna of the riparian areas of the San Antonio River.

New Park Master Plans

The River Authority has several new park projects coming to Bexar County soon! These projects will allow surrounding communities to experience nature through interpretive, recreational, and educational opportunities. Check out the projects below.

Hendrick Arnold Nature Park

Hendrick Arnold Nature Park contains seventy-four acres of riparian woodland that fronts the Medina River. Except for the creek bank, the site was extensively mined for gravel. The mining ended in 1940, allowing riparian growth to cover the area, creating one of the few remaining woodland creek properties in Bexar County. The River Authority purchased the property with plans to develop it as a nature interpretive and educational park. River Authority employees recently gave the River Foundation staff a tour of the park: Check out this great footage from the tour!

Mann’s Crossing Bicycle Park

Mann’s Crossing Park contains eighty-eight total acres. Thirty-one acres are nonoperational mining land, and fifty-seven acres are riparian woodland that fronts the Medina River. The park site was the location of Ron Pucek’s Living Waters Catfish Farm, which was closed in 2000 when the San Antonio Water System (SAWS) purchased the property. In 2013 the River Authority acquired the property with plans to develop it as a recreational and educational park.

Trueheart Ranch Nature Park

Trueheart Ranch Nature Park contains 351 acres of pecan orchards, livestock grazing, and riparian woodland that fronts the San Antonio River. The master planning effort is the first step toward a comprehensive long-range visioning process to identify areas for preservation, restoration, interpretation, and recreation, preserving as much of the site as possible.
