About H2O Hotel-Therme-Resort
Every hour on the hour a big wave of thermal water rolls into the wave pool and up its Acapulco Beach. On an island in the middle of the lazy river sits a gemstone whirlpool, and parents can sit at a pool bar in the warm water while the children play. Hotel guests walk over to the bath in their bathrobes. The adults' sauna garden has a larch sauna, a tuff-stone sauna, an Alaska plunge pool and a thermal pool of its own.
