Trueheart Ranch Nature Park contains 351 acres of pecan orchards, livestock grazing and riparian woodland that fronts on the San Antonio River. The property was purchased by James and Petra Trueheart and developed in 1848 for agricultural and irrigation purposes. The Truehearts constructed a two-story house of rock and stucco and they referred to it as “Casa Vieja” [“Old House”]. This house still remains in restored condition on the site. The master plan calls for this house to become the center of all activities proposed for the site.
This 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. The planning process began with identifying and meeting with stakeholders that currently use the park and access the river. Discussions with the stakeholders provided the planning team with great insight to the character of the site. Two 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 future development of these features.
New H-E-B Outdoor Classroom
In January 2026, a new Outdoor Classroom opened at Trueheart Ranch Nature Park, expanding opportunities for nature-based learning and community programming.
Made possible through a $130,000 donation from the H‑E‑B Tournament of Champions to the San Antonio River Foundation, the space was thoughtfully designed by Bienenstock Natural Playgrounds to encourage hands-on exploration, creativity, and environmental stewardship.
The classroom provides a dedicated gathering space for school field trips, educational programs, and community events. Using natural materials and an immersive outdoor setting, it supports interactive learning experiences that connect visitors to the river, local ecosystems, and the importance of watershed conservation.
The addition of the Outdoor Classroom further strengthens Trueheart Ranch Nature Park’s role as a destination for outdoor education—bringing together learning, nature, and the river in one place.
Little Free Library
In November 2024, a Little Free Library was installed at Trueheart Ranch Nature Park through a partnership between the San Antonio River Authority, Live from the Southside, and Lone Star National Bank. The library provides visitors with an easy way to discover new books, share favorites, and enjoy reading in a peaceful outdoor setting. Located near the historic ranch house beneath mesquite trees, the space features limestone seating and a picnic area, creating a welcoming spot for relaxation and learning. By blending literacy with nature, the Little Free Library supports community well-being and encourages visitors of all ages to connect with the outdoors while fostering a lifelong love of reading.
