Strait of Corryvreckan, is a narrow strait between the islands of Jura and Scarba, in Argyll and Bute, off the west coast of mainland Scotland. Strong Atlantic currents and unusual underwater topography conspire to produce a particularly intense tidal race in the Corryvreckan channel. As the flood tide enters the narrow area between the two islands it speeds up to 8.5 knots and meets a variety of seabed features including a deep hole and a rising pinnacle. These features combine to create whirlpools, standing waves and a variety of other surface effects.
The Corryvreckan is the third largest whirlpool in the world, and is on the northern side of the gulf, surrounding a pyramid-shaped basalt pinnacle that rises from depths of 70m to 29m at its rounded top. Flood tides and inflow from the Firth of Lorne to the west can drive the waters of Corryvreckan to waves of more than 30ft, and the roar of the resulting maelstrom can be heard ten miles away.
