Mount Pelion West, Mountain summit in Central Highlands, Tasmania, Australia.

Mount Pelion West is a 1,560-metre dolerite mountain in the Pelion Range, inside Cradle Mountain-Lake St Clair National Park. Its summit is an obelisk-shaped sloping boulder reached by a 500-metre traverse over huge dolerite blocks. The mountain rises at the eastern edge of the Murchison River catchment, with Pelion Creek below its northern side.

Mount Pelion West was first climbed on 30 January 1946 by Keith Ernest Lancaster, a pioneer of Tasmanian bushwalking, who crawled through sharp Richea scoparia scrub on the way up. He called the peak one of "The Giants of the Reserve" and described the confusion of enormous boulders on top. The mountain was named after Mount Pelion in Greece.

The name comes from Mount Pelion in Greece, the home of the Centaurs in Greek myth. The mountain lies within the Tasmanian Wilderness World Heritage Area, and the Overland Track passes within 2 km of the summit. Keith Ernest Lancaster, who made the first recorded ascent in 1946, called Mount Pelion West one of "The Giants of the Reserve".

This climb is demanding and requires experience, so allow plenty of time and preparation. Good footwear and sure footing are essential for safely navigating the steep and rocky sections.

The ascent requires navigating through roughly 500 meters of giant dolerite boulders, making it harder than nearby peaks. This boulder field demands careful climbing over irregular stone surfaces throughout much of the route.
