Unfortunately they've dried up, but there are man made "hots springs" that still draw visitors. (These hot springs are basically hot tubs sitting in a gazebo.)
While sipping an Oatmeal Porter in the Paddler's Pub on Main Street, a fellow patron noticing my hiking boots asked if I had hiked up from Greenville. This would be an odd question in any other pub, considering Hot Springs is a two drive from Greenville, but the town is a well known stopping point for through-hikers traveling via the Appalachian Trail, so it was certainly a reasonable question. The AT runs through the center of town.
Being located on the French Broad River, the town is also a popular put-in and pullout for paddlers. In addition to the various spas, there are also campgrounds, cabins and B&B's available in the town.
