The Hill country runs into west Texas right here. This is the last stop on the interstate before things just get flat and dry. That might explain why this place remains a secret. Lots of trees, lots of hills, and a river that flows clear and cold. If you ever want to go tubing without the crowds this is the place. There are publicly accessible put ins above and below the State Park and a few places in the park itself. You can have any length tubing you want. Many people choose to just float in the slower sections of the river, wade in the faster moving sections, or just hang a hammock under a tree.
