16 Best Swimming Holes in the U.S.
"The country's first national park, Yellowstone is famous for its geothermal springs. Since most of these scalding waters are too hot to swim in, the next best option is the Firehole Swim Area, located along the Firehole River and fed by thermal activity below the surface. The popular swimming area typically opens mid-summer, allowing visitors to enter the bathtub-like waters during designated hours. There are no lifeguards, so visitors will want to keep that in mind for safety and follow the regulations. To reach the location, head to Firehole Canyon Drive, located south of Madison Junction, and follow the route to the swimming location. While it might be tempting, avoid cliff jumping in the area, as it is not only dangerous but also forbidden." - Travel + Leisure Editors
