The hills of the range are the lowest and craggiest of the Galloway Hills with the highest, Mullwharchar, reaching 692m. They are split between East Ayrshire and Dumfries and Galloway along the Mullwharchar-Dungeon Hill col, following the Pulskaig Burn. Often regarded as the roughest hills in the Southern Uplands, walks can frequently take longer than anticipated due to the underfoot conditions of tussocks and bog. The range is the most remote of the Galloway Hills as the nearest road link to the north is approximately 2 miles away at Craigmalloch on the banks of Loch Doon, requiring an approach along an unclassified road. As a result, many hillwalkers begin their walk at the Glentrool Visitor Centre to the southwest and follow the path past Loch Trool to then ascend opposite the Gairland Burn and eventually to Loch Valley and Loch Neldricken. A longer but initially easier path can be followed from the same start point, following the path to the Merrick, but cutting right at Culsharg bothy and following the Buchan Burn to Loch Enoch for a clockwise round instead.
