A force to be reckoned with...
A result of the complex tidal system around the mainland and Inner Hebrides coupled with steep underwater gradients, the Corryvreckan whirlpool is said to be the second most dangerous in the world.
The Corryvreckan has claimed lives and boats throughout history; George Orwell got into bother in it in 1947, and in 1820 the PS Comet was wrecked there.
Although the Corryvreckan is still officially unnavigable,
competent local captains run boat trips there these days.
You can alternatively see it from land by driving to the end of the road (one hour from the hotel) and walking seven miles each way. Check tide tables first to ensure there is something to see as it can look very quiet.
