In Scotland, there are streams leading to waterfalls and several pools called The Fairy Pools. These magical pools are located in the south of the Isle of Skye, in a place called Glen Brittle. I have never been there, but the pictures and videos I’ve seen of the place look very serene and pastoral. And for all of the places for the ‘Fairy Pools’ to be… a place called the Isle of Skye seems pretty appropriate.
Here is a walking guide if ever you happen to be in the area http://www.walkhighlands.co.uk/skye/fairypools.shtml
In the video below, the reporter states that there are Rowan trees surrounding the area, which is a tree sometimes used for protection. She also states that selkies may be associated with the area, but she doesn’t go into any tale explaining why the place is called the Fairy Pools.
And here is a photo of the pools by photographer Julian Calverley, the picture is linked to his site.
