Best place to get away on a hike or just to enjoy nature. Closest feel to being in the woods right outside the city you will get for Dallas. Been going here for years.
If you go, only thing you should keep in mind is that alot of visitors unfortunately blast their music on the hike or are very loud and disruptive of the peaceful nature enviornment. Not sure if they want to enjoy Nature why they feel the need to do this, but if you can get away from them it is a lovely experience.
