Easdale Slate Quarry Pool

Easdale Island is the smallest permanently inhabited island in Scotland (7 minutes by ferry from Seil, the "Island Over the Bridge") and its flooded 19th-century slate quarries are one of the most unique swim locations in the UK. The quarry pool is a rectangle of calm, blue-green water surrounded by abandoned slate workings, warm on sunny days thanks to the dark stone absorbing heat. The World Stone Skimming Championships are held here annually on the last Sunday of September. The water is surprisingly warm for Argyll.

Getting there
