USA/AR: Hot Springs National Park
Hot Springs National Park preserves the historic part of the town of Hot Springs in Arkansas. The thermal water have been used for medicinal treatment here for centuries, and elaborate bathhouses grace the town center. There are a total of 47 springs pumping over 1,000,000 gallons (3,800,000 liters) of scalding water at 143 °F (62 °C). The water then flows to Bathhouse Row where most of the historic bathhouses are located, the most famous being Buckstaff, Quapaw, and Lamar. Naturally, taking a bath is a must-do here.
