Follow the Earnslaw Burn Track through bush to the tussock basin at the head of this valley. This will bring you to a viewpoint with impressive views of an icefall on Mt Earnslaw/Pikirakatahi at the edge of the forest where the track ends.
Although a Marginal Strip exists along the Earnslaw Burn stream, the valley and tussock basin beyond this viewpoint sits on Earnslaw Station which has no right of access. An overhanging rock just within the forest on the true right (looking downstream) of Earnslaw Burn can be used for shelter.
River crossing and route finding experience is essential. There is also windfall and slips along the track that you need to get over.
The track starts on the true left bank of the Earnslaw Burn partway along Lovers Leap Road, a right turn off the gravelled Glenorchy - Paradise Road, 20 minutes from Glenorchy.
The track can be tricky to find in places and the river crossing to get to the bivvy is dangerous in heavy rain. This track is not recommended for young children.
