Mount Twynam is a mountain located on the Main Range, part of the Great Dividing Range, in the Snowy Mountains in New South Wales, Australia. The mountain is located close the border between New South Wales and Victoria.
With an elevation of above sea level, Mount Twynam is the 3rd-highest mountain on mainland Australia. It is located north-east of Mount Kosciuszko.[3]
The mountain is large but unimposing, and has good and far-reaching views over Blue Lake Cirque and the Western Falls. Despite being relatively accessible by track, it is rarely visited.[4] The mountain forms a watershed for the Snowy River to the southeast and the Geehi River to the northwest.[2]
