In the Ouachita Mountains, it feels almost more like a National Forest than a National Park. It protects the Hot Springs from which it gets it's name.
Several hot springs exist in the park and the water from them is sterile. In the city of Hot Springs, they have a distribution point where any body can take jugs and fill them with the water from the springs.
The Hot Springs Mountain Observation Tower gives a very beautiful scenic overlook of the park and Hot Springs, the town.
Within Hot Springs, Fordyce Bathhouse offers displays of bathhouse history and also tours of the bathhouse, explaining how they came to exist and how they were used.
