Lake Mountain is a 1,433-metre-high mountain peak on a plateau that hosts a cross-country ski resort that is known by the same name. It is located in Victoria, Australia, approximately 120 kilometres north-east of Melbourne.
The 1,483-metre-high Mount Bullfight, which is within the Mount Bullfight Nature Conservation Reserve, is the highest peak that can be reached by a cross-country ski trail from Lake Mountain. Access to Lake Mountain's summit is restricted to a snow shoe track in winter.
The Lake Mountain Alpine Resort, located near Lake Mountain, is the most popular ski resort in Australia when measured in terms of total visitor numbers, including sightseers, due to its proximity to Melbourne. The Lake Mountain Alpine Resort is surrounded by the Yarra Ranges National Park into which its ski trails lead.
The resort is an unincorporated area under the direct administration of the government of Victoria, and is surrounded to the west, north & east by the Shire of Murrindindi and Yarra Ranges Shire to the south.
There is no lake at Lake Mountain. It is claimed that the mountain was named after George Lake, who was the surveyor-general of the area. Contradicting this, VICNames says that it is named for the "tarns, ponds and bogs near the summit".
