Dun Mountain Walkway, halfway between Maitai Dam and Coppermine Saddle. The western edge of the mineral belt on Wooded Peak is easily distinguished by the sudden change in vegetation from low scrub to beech forest.
Looking west across Tasman Bay from the summit of Dun Mountain, Nelson. Fringed Hill is straight ahead and you can just make out Port Nelson to the right of it. Dun Mt is a great day walk through the amazing landscape of the mineral belt (the summit is 5-7 hrs return from Maitai Valley road end).
The track to Whispering Falls branches off of Hacket Track. The use of 'falls' in their name is slightly misleading; they are more of a dribble (except after rain), though the misty water droplets and mossy rockface are pretty nonetheless. There's a good picnic spot in the clearing above the falls.
Hacket Track crosses the Dun Mountain ophiolite belt, where outcrops of ultramafic rock rich in minerals like chromite, olivine and serpentine are revealed. This is a really interesting half-day walk within half an hour drive of Richmond.
