Loch Treig is a deep freshwater loch situated in a steep-sided glen 20 km (12 mi) east of Fort William , in Lochaber , Highland , Scotland . [ 1 ] While there are no roads alongside the loch, the West Highland Line follows its eastern bank. Loch Treig was originally a natural freshwater loch over 400 feet (120 m) deep. [ 1 ] In 1929, Loch Treig was made into a reservoir , retained behind the Treig Dam , forming part of the Lochaber hydro-electric scheme , which required diversion of the West Highland Railway . [ 2 ] The increase in water level following the construction of the dam submerged the hamlets of Kinlochtreig and Creaguaineach at the loch's southern end, which were stopping points on a cattle drovers' road along the Road to the Isles, which linked up Lochaber and the Inner Hebrides to markets in Perthshire in the south. Ken Smith (b. 1947), a self-described hermit , has lived alone in a rough cabin on the shore of Loch Treig for forty years. [ 3 ] He was profiled in the documentary The Hermit of Treig (2022), and wrote the memoir The Way of the Hermit (2023). [ 3 ] [ 4 ] Laura Miller opined in 2024, he "may be the most famous living hermit in Scotland".
