Overlooking Norra Lake in Central Sweden, west of Stockholm, this family-owned spa dates back centuries. First made famous for its legendary cures in the 18th century, including ridding a king of his migraines, the destination continues to attract health-conscious pilgrims. Occupying a group of historic, restored structures, the tony country house hotel features a Water Salon on the lake’s shore with aqua therapy elements, treatments and saunas. A centuries old, still flourishing herb garden yields produce for the kitchen, while its Health Resort Museum presents the history of Swedish wellness trends.
