The hills of the range are the second lowest of the Galloway Hills with the highest hill, Lamachan Hill, reaching 717m, but cover a much more circular area. They are located entirely within Dumfries and Galloway and, despite the name, are most commonly ascended from nearby Glen Trool to the north, albeit more steeply, rather than Minnigaff itself to the south. A common round takes in Lamachan Hill and Curleywee with the option of Larg Hill, however the most easterly and isolated Donald, Millfore, is normally ascended on its own. The higher summits broadly form an 'N' shape and contain far more divergent satellite ridges and individual hills than the other three ranges.
