We did this walk the morning we arrived on the ferry from Melbourne, as it was on our way to Hobart via a scenic route over the Central Highlands. It starts off in attractive myrtle beech forest, passes through large boulder fields, more forest, then up onto the summit plateau which is heathland. About 6km/500m of sometimes steep climbing to 1228m above sea level. There are good views of the Great Western Tiers and farmland to the north. We also visited nearby Liffey Falls (a short drive away).
The track is marked and so easy enough to follow, although I did get lost at one point in the beech forest, but the markers are there so just be vigilant. We used notes in Day Walks Tasmania. Online the walk is described on Tas Trails and some other sites.
