Great Langdale
（重定向自Langdale）
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 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. One of 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 spectacular views of, in particular, Dungeon Ghyll Force waterfall, Harrison Stickle and the Pike of Stickle.
