Fodor's Expert Review Wandelhalle

Hotels here base spa treatments on the health-giving properties of the saline springs and the black mud from the area's waterlogged moors. The elegant, pillared pavilion of the attractive spa gardens is really a sight to behold, with its unusual misting green facade, said to extract salt from the water. All you need to do is walk along the 540-foot Gradierhaus, a massive wood-and-concrete construction that produces a fine salty mist by trickling brine down a 40-foot wall of dense blackthorn bundles (breathing salt-laden air is a remedy for various lung conditions).
