Fionn Loch is a small irregular-shaped shallow freshwater loch, on a north-west to south-east orientation that is located 3 miles southeast of Lochinver[1] [2] [3] in the Assynt district of Sutherland in Scotland. The loch is located in an area known as the Assynt-Coigach National Scenic Area,[4] one of 40 such areas in Scotland.[5]
Fionn Loch is part of the Fionn Loch drainage system and is fed with water from River Ledbeg which drains Loch Urigill, due south-by-south east and Loch Borralan, to the east of Urigill.[6] Loch Veyatie directly south, drains through Uidh Fheàrna, a slow-moving channel into Fionn Loch.[6] The drainage system was once a large lake, Loch Suilven that is now made up of Cam Loch, Veyatie and Fionn Loch.[6] A vast number of lochs and lochans surround Fionn Loch, the biggest is the large irregular-shaped Loch Sionascaig along with Inverpolly Forest directly south.
Overlooking the loch to the north-west is the imposing hulk of the mountains of Suilven at 731 meters.[7] Almost directly south of the loch is Cùl Mòr at 849m and Drumrunie Forest. To the far north-west is Drumrunie Forest.
Fionn Loch is remote and can be reached from a route that starts from Inverkirkaig, this route reaches the bealach from the south, passing Kirkaig Falls on the way.[8]
