Hot Springs, Arkansas has been drawing visitors for centuries, and it all starts with the water. The city sits atop a natural thermal spring system that produces nearly a million gallons of 143-degree water each day.

Some, like the Fordyce Bathhouse, now serve as museums, while others still offer traditional thermal soaks.
