Hendrick Arnold Nature Park

Hendrick Arnold is open to the public and currently has several trails available to explore. “Daniels Loop”, “Medina Trail”, and “Rachels Trail” are open at the park. 

Hendrick Arnold Nature Park contains 74 acres of riparian woodland that fronts on the Medina River. The site, with the exception of the creek bank, was extensively mined for gravel. The mining ended in 1940 allowing riparian growth to cover the site creating one of the few remaining woodland creeks properties in Bexar County. The San Antonio River Authority purchased the property with plans to develop it as a nature interpretive and educational park.  This master planning effort is the first step toward a comprehensive long-range visioning process to identify areas for preservation and interpretation while preserving as much of the site as possible.

Four alternative concepts were developed utilizing a workshop process to establish priorities, develop concepts, and build consensus. These plans were presented at a public meeting and ranking was developed for features to be included in the master plan and also to set priorities for the development of these features. The park should have a number of management zones including a river / riparian zone, a forest and wildlife zone and an activity zone.  Within each of these zones, different maintenance, management, and improvement guidelines and levels were recommended.

Mission Reach Area Maintenance

When: Beginning October 20, 2025 through Spring 2026 What: Crews will be performing stem-density removal and related vegetation maintenance along sections of the Mission Reach to help manage flood risk and protect surrounding infrastructure. Some trails or segments may be closed temporarily while work is underway. Why: Removing excess stems that naturally establish along the river helps maintain stormwater conveyance, reduces flood risk, and protects public infrastructure while allowing grassland and native vegetation to recover and thrive. What to expect:
  • Limited trail closures and intermittent work zones.
  • Crews and equipment working near the riverbanks during daytime hours.
  • Parking areas remain open, but visitors may see signage and temporary barriers.
