The Corryvreckan Whirlpool is a mile of swirling, turbulent water that separates the Scottish Inner Hebrides island of Jura from northerly Scarba. Rumour whirls around this murky place, they say it is the third largest whirlpool in the world, that the Royal Navy classify it as officially ‘unnavigable’, that an unfortunate Norse king was swept to his death here at some point, and that George Orwell almost drowned here. But still a few hardened swimmers take up the challenge, having about half an hour to swim the mile before the tide changes. I like it! :-) Via blog.bestwestern.co.uk.
