Karlovy Vary is the most famous Spa town in Czech, with natural mineral springs spread out in the town. There are about 6 Spa locations in town, and many services and swimming pools use mineral spring water. The city is also known for the Karlovy Vary International Film Festival, and it hosts many culture, social, and sport events during the year. The one we went to, ZAMECKE LAZNE, is the most upscale one. It offers a very comprehensive list of services, with some services and facilities I never saw in any place else. We spent 3 hours in Spa, very refreshing.
