Glen Brittle is a large glen in the south of the Isle of Skye, in Scotland. It runs roughly south to north, along the River Brittle, which has its mouth at Loch Brittle. The glen is also overlooked from the east by the formidable Cuillin, the largest mountains on Skye. Many tributaries of the Brittle run down from these mountains into the glen, including a stream with waterfalls known as the Fairy Pools, a popular place to go for a walk. Because of its location by the peaks, the area is popular with hikers and mountain bikers.
