Australia’s third highest mountain (and trig station) is located on the Kosciuszko Main Range, at a height of 2,195.3m, above sea level – although some older maps show the height as 2,196m. Mount Twynam offers a view of many of the highest peaks in Australia, including Mount Kosciuszko, Mount Northcote, Muellers Peak and Rams Head North to the south-west.
To the north-east along the Main Range and the Rolling Grounds is Dicky Cooper Bogong and Gungartan, with Round Mountain in the distance.
To the west is Tenison Woods Knoll (2,136m) and Watsons Crags.
Mount Twynam is named after Edward Twynam, the Chief Surveyor for NSW in the 1890s, who came out to Australia in 1855: “He carried out the original survey, and, in a great measure, the exploration of the Lachlan and Darling Rivers, also the survey and lay-out of the base line for the trigonometrical survey of New South Wales.” There’s a trig station at the highest point of Mount Twynam’s large summit area, with the official trig point being a “Brass Plug in Rock”.
Getting to Mount Twynam
Mount Twynam (and Little Twynam) is easily reached from Charlotte Pass as a day-walk:
- as an “out and back” walk via the Main Range Walking Track – 16.1km (700m elevation gain)
- as a loop walk by combining the Main Range Walking Track with a walking track down to the Illawong Swing Bridge and the Snowies Alpine Walk along the Snowy River – 18.7km (840m elevation gain).
Alternatively, from Guthega you can do a loop via Consett Stephen Pass and Mount Tate, with a detour to Mount Twynam. This is about 23km with 940m elevation gain.
You can also visit Mount Tywnam as part of a multi-day Top Ten Peaks walks, which traverses the highest peaks of the Main Range.
