Piz Quattervals: The roof of the National Park

The route leads from the romantically situated Chamanna Cluozza (overnight stay) through the Valletta to Piz Quattervals. The ascent is considered alpinistically challenging. Ibex can often be observed on the rocks and a ground at almost 2500 m above sea level offers in July a diverse alpine flora with Mont Cenis bellflower, creeping carnation root and stemless catchfly. From an altitude of 2500 m above sea level, the trail markings disappear. It is stipulated that Piz Quattervals may only be ascended from Val Cluozza via the side valley Valletta. Other routes are not permitted. Caution, especially in high and late summer, Piz Quattervals is considered prone to falling rocks.

Note: Bringing dogs is not allowed in the Swiss National Park, not even on a leash. Further information on this and all protection regulations can be found at nationalpark.ch/protection-regulations.

From Zernez train station (1474 m above sea level) through Val Cluozza, the oldest part of the Swiss National Park, to Chamanna Cluozza (see route Chamanna Cluozza). Before ascending Piz Quattervals, overnight stay at Chamanna Cluozza (1862 m above sea level) – advance booking is strongly recommended (www.cluozza.ch/ Tel. +41 81 856 12 35).

From Chamanna the route first descends to Ova da Cluozza, crosses the stream (1835 m above sea level) and leads into the Valletta. There the path initially follows the stream and then steadily climbs along the western valley flank. The lower rock ridge (2200 m above sea level) is bypassed on the right, the upper one (2400 m above sea level) is climbed over. The further path leads over a wide block glacier and reaches in high summer at about 2700 m above sea level the first snowfields. In early summer, when hard snow still covers the entire northern flank of Piz Quattervals, a route directly from the north is advisable from here. With stronger thawing it is recommended to climb the northwest ridge and reach the summit via point 2985. For the ascent, areas with little debris should be chosen (danger of falling stones caused by preceding alpinists). After fresh snowfall, any avalanche danger must also be considered when crossing the north side. The path over the northwest ridge leads over block debris and rock bands to the summit (3165 m above sea level). The return route goes over the northwest ridge or directly over the northern flank again through the Valletta back to Chamanna Cluozza.
