The maelstroms are created when the tide turns and flows in and out of the strait between the two fjords Saltenfjorden and Skjerstadfjorden. Every six hours, 400 million cubic meters of water will cross the 3km long and 150m wide strait at a speed of up to 20 knots. This creates enormous forces in the form of whirlpools that can be up to 10 m in diameter and 4-5 m deep.
Visit Saltstraumen when the current is at its strongest and admire the enormous forces of Mother Earth. The time of when this is varies from day to day. We recommend that you check the Saltstraumen time table to see which times apply on the exact day you are visiting.
