An easy-going dirt road, closed to traffic, skirts Lake Toggia and takes you all the way to the San Giacomo Pass. Built in 1929, the road had aroused fears among the Swiss of belligerent intentions.
All that is in the past: today it is a place of utter peace and tranquillity. Just below the pass is a white-plastered chapel, namely the oratory of Saints Nicholas, Catherine and James, the last remaining trace of a hospice that stood there in the Middle Ages, welcoming wayfarers, pilgrims and merchants crossing the Alps. Here, too, are lakes and watercourses. From here, a narrow path climbs up a barren scree slope to the Grandinagia Pass (2698 metres) - the final destination of the entire trek. As you descend, you will see the Robièi basin from a different perspective. Then, passing Lake Sfundau, you will climb up to the Cristallina mountain hut, a milestone in modern high-altitude architecture, newly built and inaugurated in 2003. There is nothing more beautiful than to watch the sun set from its terrace.
