Ironstone Mountain, Mountain summit in Great Western Tiers, Tasmania, Australia.

Ironstone Mountain is the highest peak of the Great Western Tiers, reaching 1,444 metres (4,738 ft) above sea level in Tasmania's Central Highlands, south of Mole Creek. Its highest point carries a trig point, while the slightly lower summit shown in photographs is more prominent. Lake Ironstone lies nearby.

The mountain formed through volcanic activity and glaciation spanning millions of years. These processes created the rocky structures visible today throughout the Great Western Tiers.

The two approach routes carry walkers past Western Creek and the slopes south of Mother Cummings Peak, both named landmarks in the Great Western Tiers. The summit's trig point and the slightly lower signal peak shown in photographs are the features walkers aim for.

Two walking tracks reach the summit: a northern route via Caveside and Westrope Road, and an eastern path from Smoko Road. Visitors should wear sturdy footwear and prepare for changing conditions since trail surfaces vary with the seasons.

A marked trig point marks the highest point of the mountain and serves as a landmark for hikers. Near the mountain's base sits Lake Ironstone, a natural body of water that complements the peak in the broader landscape.
