The 28 km (17½ mile) by 16 km (9.9 mi) Benmore Range is aligned approximately north–south and situated between the small town of Twizel at the northern end and the village of Omarama at the south-western end. The Benmore Range is bordered by Lake Benmore to the south and the Haldon Arm of Lake Benmore to the east.
There are more than thirty surveyed peaks above 1,000 m (3,280 ft), with at least twelve of these above 1,500 m (4,920 ft), although only five have official names.
Benmore Peak (1,932 m / 6,338 ft) is near the centre of the range, with Sutherlands Peak (1,846 m / 6,054 ft) and The Cairn (1,464 m / 4,801 ft) to the north and Totara Peak (1,822 m / 5,977 ft) to the south. The Buscot (1,245 m / 4,084 ft) is an attached subpeak on the western side of the main range.
Although it is almost entirely New Zealand Crown land and a protected Outstanding Landscape Area, several large farm stations have legally run stock on the Benmore Range for more than a century, including Ben Omar, Benmore, Buscot, Glenbrook, Glencairn, Peak Valley and Totara Peak.
The NZ Department of Conservation acquired 12 km2 (1,200 hectares / 2,965 acres) of land between The Cairn and Sutherlands Peak from Glenbrook Station and it has been officially designated a public Conservation Area. It incorporates an area of wetlands as well as much drier elevated areas. A public walking track is accessible via an easement across Glenbrook Station.[1]
