SodiumChloruresBrome

Marstrand Spa Bohuslän is located on the car-free island of Marstrand, a jewel of the Swedish Bohuslän archipelago dominated by the imposing 17th-century Carlsten Fortress that overlooks the sea. The spa harnesses chloride-rich seawater from the Kattegat for revitalising thalassotherapy treatments, continuing a wellness tradition that drew European royalty and aristocracy to Marstrand during the 19th century when the island was the most fashionable bathing resort in Scandinavia. Today, guests enjoy salt-water pools and marine-mineral body treatments while soaking in the maritime atmosphere of one of Sweden's most historically distinguished coastal towns.

Insider tip — Marstrand Spa is set on a car-free island off the Bohuslän archipelago, where heated seawater pools and Atlantic breezes define the experience. The sodium-chloride thalasso treatments at 38°C harness the mineral richness of the North Sea. The island is dominated by the 17th-century Carlsten Fortress, whose silhouette frames sunset dips from the outdoor pool. Book a combined sailing and spa package for the quintessential Swedish west-coast experience.
