Trolleskär sits about as far west as the Swedish coast reaches, a skerry on the western edge of Väderöarna that can only be dived when conditions allow. Walls and large boulders run down to 26 m, and the current that sweeps them feeds dense growths of dead man's fingers and sea anemones. On a good day it ranks among the best dives in Sweden.
Also known as Trollskär.

The dive
