This is a bit of a classic Nelson back country loop. This route goes from Brook Street, up to the Dun Mountain Saddle, then to the summit of Dun Mountain, down to the Little Twin climb, to Little Twin summit then dropping down via Dew Lakes to the Maitai Dam and back along Maitai Valley Road. Give it between 5-7hrs depending on fitness, weather and if you want to hang around at the top. It's very exposed on the summit of Dun Mountain so definitely take a god amount of kit. EPIRB recommended as well as usual back country planning stuff. The descents are grade 5 and well worth the trip. Scenery goes from native to alpine, to native and everything in between. No signs after Dun Saddle so be prepared with map/offline route etc.

Basic overview - ride up Dun Mountain Trail to the saddle (grade 3), then carry up to the Dun Mountain summit, descend from summit (grade 4), ride/hike up Little Twin, descend Little Twin (grade 5) to Dew Lakes. Descend Dew Lakes (grade 5) to Maitai Dam. Ride back to Nelson on the Maitai Valley Road.
