The Heinzenberg Ridge begins in the south with the 1848 m high Glas Pass, a historically significant bridle path connecting Thusis to the Safien valley. A trail exists along the ridge, which provides nice views of the valley. The highest points along the trail are Lüschgrat (2179 m), Tguma (2163 m) and Präzerhöhi (2120 m). To the west, the ridge falls off abruptly into the Safien valley.
