From the north shore of Lake Nerine, walk to the west side and climb to the low saddle. From here, there are two routes to North Col.
The low route descends to the 1440m ledge and contours around to the gully below North Col - then up. There are useful cairns along the route.
If visibility is questionable, use the low route. The high route takes slightly longer (and would be very challenging in poor weather).
