West Baden Springs, IN–The Sprudel Bath at the Spa at West Baden Springs takes you back to historic beginnings of the hotel. Here you can partake of the healing waters, filled with 22 minerals that give off hydrogen sulphide and carbon dioxide gas. The nose may wrinkle at this old-fashioned odorous soak, but oh, it is soothing. And it couldn’t be presented more beautifully in a private bathing room in the 14,000 sq. ft. spa. At $45 for a 25-minute soak, it’s one of the less-expensive treatments, and still includes time in the relaxation room and sauna. The mineral waters are reputed to relieve stress and pain, and I have to say I emerged a little shaky in the legs. Check out the crusty minerals–calcium carbonate, calcium sulphate, magnesium sulphate, among others–on the cold water tap. And if you’re tempted to sip a cup, just know that it does affect the digestion. “Pluto water” from the springs was once bottled and sold under the tagline, “When nature won’t, Pluto will.”
