Loch Coruisk (in Scottish Gaelic, Coire Uisg, the "Cauldron of Waters") is an inland fresh-water loch, lying at the foot of the Black Cuillin in the Isle of Skye, in the Scottish Highlands.
The loch is accessible by boat from Elgol, or on foot from Sligachan (approximately 7–8 miles’ distance). It is also possible to walk from Elgol, but one section of the path (“the Bad Step”) presents some potential difficulties for the nervous or inexperienced.
The northern end of the loch is ringed by the Black Cuillin, often wreathed in cloud. From the southern end a small rivulet, approximately 250 yards long, discharges into a sea loch, Loch Scavaig. The loch is nearly two miles long, but only a couple of hundred yards wide.
