The Moskenesstraumen is one of the strongest tidal currents in the world — a maelstrom off the southern tip of Moskenesøya where the tidal flow between the island and the small island of Mosken creates violent whirlpools and standing waves several metres high when conditions peak. The current runs at up to six knots at spring tide.
Organised boat trips from Sørvågen and Reine venture out to experience the Moskenesstraumen at close range. The same boats also reach the Kollhellaren cave at Refsvika on the western coast, which contains cave paintings approximately 3,000 years old and is accessible only by sea.
