The range is east of the main line of the West Coast Range and runs at right angle to it in a west–east direction. It is separated from that range by the King River valley and is bordered by the Eldon River to the north and west.
A smaller peak to the south is known as the Little Eldons, with an elevation of 640 metres (2,100 ft) above sea level and it is separated from the Eldon Range by the South Eldon River.
In the 1860s report of travels of Charles Gould, the Eldon range is mentioned.[9]
In the 1930s Eldon Peak was used as the starting point of a walk by F Smithies of Launceston and C Bradshaw of Linda.[10] In 1991 Crawford and Reid's climb is found described in Crawfords book on the King.[11]
Eldon Peak is one of the least visited peaks in Tasmania due to its remoteness. It was climbed in 1947 by Keith Lancaster, a Tasmanian bushwalker who recorded a cairn on the summit, indicating it was not the first European ascent.[12] Lancaster ascended from the King River valley, a route no longer possible due to the impoundment of the river. Modern approaches would be from the south-east or south arriving at Lake Ewart at the foot of Eldon Bluff. All approaches are over trackless terrain with patches of difficult scrub.
Part of the route from the south east follows the western border of the Cradle Mountain-Lake St Clair National Park, marked with poles by the bushman Charlie Spencer. Few of the poles still survive, and could not be relied upon. Navigation in this area would be extremely difficult in poor weather.
