Saratoga, New York

Legendary for its healing waters long before Europeans discovered the New World, Saratoga Springs continues to draw people from around the world who are curious to test out the springs' restorative powers. You don't go swimming in the springs themselves and the hotels that pipe waters in aren't exactly what you might call luxurious. The most famous is the Roosevelt Baths at Gideon Putnam Resort. This is where FDR used to go for hydrotherapy, and the setting hasn't changed much since his day. Patrons recline in individual soaking tubs located in small, simple private rooms, and soak in the effervescent, unnervingly brown water for approximately an hour.
