Dun Mountain

Dun Mountain is a summit standing at 1,129 meters near Nelson, with reddish soil and sparse vegetation covering its upper slopes and exposed rock faces. The barren character of the peak makes it stand out clearly in the surrounding landscape.

The peak was first studied scientifically in 1859 by Ferdinand von Hochstetter, who identified a new rock type within it and named it dunite. This discovery established it as an important site for geological research.

The peak gets its name from the distinctive yellowish-brown color that early Nelson settlers noticed when looking at the exposed rock and soil on the slope.

A mountain bike trail of roughly 38 kilometers starting from Nelson connects to the summit and covers varied terrain along the way. Visitors should prepare for changing conditions, especially on the exposed upper sections where weather can shift quickly.

The mountain serves as the reference location for two rock types found nowhere else in such distinctive form - dunite and rodingite - making it a globally important site for geologists. Scientists travel here specifically to study these mineral formations and collect samples.
