What to do in Hot Springs National Park: Nearly 200 years old, Hot Springs National Park is, technically, the first federal reserve in the nation, predating Yellowstone National Park. This natural gem, found in the lush forests of Arkansas, is likely one of the main reasons to drive through Arkansas in the first place. The town of Hot Springs itself was built right into the park.
Plunge into the warm, bubbling pools along Bathhouse Row, including Buckstaff Baths, which has been open since 1912, or marvel at the architecture at Ozark Bathhouse. You can also scale the Hot Springs Mountain Tower, which offers panoramic views of the Ouachita Mountains.
