Loch Laggan is located near Fort William, in Lochaber, Highland, Scotland. It has been a reservoir since 1934, retained behind the Laggan Dam, making part of the Lochaber hydro-electric scheme. Kinloch Laggan borders the lake. The entire area is ruggedly mountainous and is weak populated. On the east part of the loch a freshwater beach can be found, the widest one in Britain, and a well known resort with swimming, canoeing, fishing. Apart from the loch, the Cairngorms National Park can be easily accessed, the largest national park in Britain.
