With a name like Sulphur, this once-mining town has turned into a tourist destination for its water features. Take a hike down the Travertine Trail, where Oklahoma's largest artesian spring resides. In the olden days, visitors smeared the sulphur-rich mud on themselves for its healing properties. Stay a night at the Historic Artesian Hotel and Casino, where famous guests like the 27th President of the United States, William Howard Taft, and famous Western Actor John Wayne stayed. With springs, a mountain range, and many parks and lakes, Sulphur is known to tourists for its outdoor activities.
