Scenically, this is a true gem of a mountain in the Swiss Alps. However, the Julier Pass is very busy. Therefore, it's advisable to take the alternative route from Tiefencastel via Mon and Salouf to Cunter for the first section. This road has very little traffic, is excellently paved (standard paved), offers excellent climbing with magnificent views, and, most importantly, avoids the rather unpleasant Crap Sers Tunnel on the main route when approaching. There's also an additional 150 meters of elevation gain, which is rewarded with a refreshing downhill section before Cunter.

Gentle and flat to the east, steep and somewhat exposed to the west. This is how the pass between the Heinzenberg and the Safiental appears.
