This exciting one day ride from Nelson climbs onto the flanks of Dun Mountain on New Zealand’s first railway line, before descending for over 20km back to Nelson.

The Dun Mountain rises to 1129 metres and, due to its unique geology, is one of the most distinctive mountains around Nelson.

Early sections give glimpses of the Waimea Plains to the south and west. More extensive views can be enjoyed back across Nelson and beyond to Tasman Bay and Abel Tasman National Park.

Third House is a good place to pause for a break and a chance to listen to bellbirds or be entertained by ever-inquisitive wekas.

The trail’s emergence on to the mountain tops near Windy Point and Coppermine Saddle offers stunning views of Tasman Bay, followed by one of New Zealand’s longest mountain bike downhills.

Access Info

About 1km from down town Nelson you'll find the start of the Dun Mountain Walkway signposted just past 135 Brook St.

 Amazing track, a must-do for keen intermediate-advanced riders. Requires a good level of fitness. Be aware the descent is rough and rocky in places and that the trail is multi-use - expect to encounter other riders and hikers on the descent.
