The summit is at 1,271 metres and you can drive there from the city in 30 minutes — one of the very few capital-city mountain summits in the world that you can simply drive to. The view takes in the entire city, the Derwent estuary, the Tasman Peninsula, Bruny Island, and on a clear winter day the snowy peaks of the southwest wilderness. There is an enclosed viewing platform and an open lookout that is genuinely cold most days of the year. Bring more layers than you think.
For walkers, the network of tracks on the eastern face is excellent: the Organ Pipes Track along the cliff base, the Pinnacle Track from the Springs car park to the summit (a 2-hour climb), and the easy Lenah Valley Track through fern forest. The Springs, halfway up, has a kiosk and is the starting point for several walks. Snow on the summit is common from May to October and the road closes when icy.
