From the Whataroa valley, Gunn Ridge gives access to the Price Range and Tartare Range, via the upper Gunn River. There are good campsites in the upper basin of the Gunn River.
Whataroa River to Gunn Ridge
DOC has closed the tracked spur onto the ridge from Butler Junction in the Whataroa valley, due to severe erosion. It may be possible to gain the ridge using the spur north of McCormick Creek, over Pt 825 metres, which is less steep. This was reported as scrubby but reasonable going, as is McCormick Creek lower down.
Gunn Ridge to upper Gunn River
Follow Gunn Ridge up to 1700 metres, then descend the valley that heads north from Pt 1854 metres to about the 1560-metre contour. From here sidle mostly west, crossing streams and climbing to 1700 metres again before swinging north-west down broad tussock slopes to lower flats in the upper Gunn basin.
