The Rough Bounds (Scottish Gaelic: Na Garbh Chriochan), in the Scottish Highlands, is the area of West Inverness-shire bounded by Loch Hourn, Loch Shiel, and Loch Moidart, consisting of the districts of Knoydart, North Morar, Arisaig and Moidart. The area is famous for its wildness and inaccessibility and remains very sparsely populated.
An anonymous writer in 1750 commented that "all these countries viz. Knoydart, the Two Morrirs, Moydart, and Arisaig, are the most Rough Mountainous and impassible parts in all the Highlands of Scotland, and are commonly called by the Inhabitants of the Neighbouring countries the highlands of the Highlands."[1]
