A short boardwalk to a lookout over a tunnel/cave that leads out to sea.
A short loop around the blowhole and out to a lookout over the coast.
A one day “express” version of the new Three Capes Track in Tasmania, on the Tasman Peninsula - this route covers 90% of the official "Three Capes Experience" track, and could also be done over two days camping at he only designated campsite.
An easy short walk starting very close to the Tasman Arch down to the Devils Kitchen and ending at Waterfall Bay Lookout.
Nice walk on coastal cliffs past a little waterfall and out to the bluff.
Moderate hike. Starting on private property gate, through magnificent myrtle forest alongside a creek, to a steep zigzagging fire trail to a fun top scramble to the summit. Fantastic views and a fairly sheltered hike until you hit the top. Return the same way or alternatively keep walking along the ridge to the Montague Thumb and come back in a long loop across the valley.
The "Sleeping Beauty". Start at Collinsvale and finish at Big Bend (Mt. Wellington). This needs a drop-off and pick up.
A truly rewarding half day hike.
Overall a moderate walk but given the wet and slippery mud at the beginning and the nasty weather that can occur without warning it can be considered a difficult hike.
At 1,270m, Mt. Wellington provides absolutely stunning views of Hobart and the surrounding area, the Derwent Estuary, Storm Bay and beyond.
