Be sure to bring soap. Didn't know what to expect. These are mineral springs. They will furnish a towel, but not soap. smelled like sulphur the rest of the day.[Mylak, 07/14/2012]
The dinosaur is located at the entrance to Hot Springs State Park.[Joe Boulter, 09/25/2011]
Two parts, one a state park with large travertine terraces and picnic area. There is a free soaking pool ("state bath house"). There are also several commercial hot spring pools with waterslides. Lots of fun for children, but take water shoes, as the warm water and mineral deposits are like sandpaper on the soles of your feet.[George, 05/15/2006]
