With cool aquamarine pools created from the picturesque Pedernales River shaded by towering cypress trees, this park brings a respite from the glaring sun on hot summer days, especially if you're here to partake of one of its water-based activities like swimming and tubing. If you're here to burn calories with a long trek, you've also come to the right place. Hikers and mountain bikers can embark on 19.8 mi of trails, with an additional 14 mi of backpacking trails (hiking
only). Fishing, bird-watching, picnicking, and camping are also popular here. Park facilities include picnic sites, restrooms (some with showers), a trailer dump station, and campsites (some with water and electricity, others that are primitive and must be hiked to, with a 2-mi or longer hike). No pets are allowed at the park.
