Great Langdale is a valley in the Lake District National Park in North West England, the epithet "Great" distinguishing it from the neighbouring valley of Little Langdale. Langdale is also the name of a valley in the Howgill Fells, elsewhere in Cumbria.
It is a popular location for hikers, climbers, fell-runners and other outdoor enthusiasts who are attracted by the many fells ringing the head of the valley. Among the best-known features of Great Langdale are the Langdale Pikes, a group of peaks on the northern side of the dale. England's highest mountain, Scafell Pike, can be climbed by a route from Langdale. Langdale has views of, in particular, Dungeon Ghyll Force waterfall, Harrison Stickle and Pike of Stickle.
