The park is an outstanding example of Edwards Plateau flora and fauna. It is a combination of steep, rugged limestone canyons; springs; plateau grasslands; wooded slopes; and clear streams. It features a large, isolated stand of uncommon Uvalde bigtooth maple, whose fall foliage can be spectacular. Generally, the foliage changes the last two weeks of October through the first two weeks of November. The park is extremely popular during the fall and is often crowded.
