Plateau Rosa is on the border between two Alpine valleys: Valtournenche in the Aosta Valley and Mattertal (or Zermatt Valley) in the Valais Canton of Switzerland. It is a strategic logistical site for the Matterhorn Ski Paradise, between Breuil-Cervinia and Zermatt.
In winter, skiers arrive on the Italian side via the Cime Bianche-Plateau Rosa cable car and on the Swiss side via the Tête Grise. The Zermatt Bergbahnen company plans a new connection between the Klein Matterhorn (Little Matterhorn) and Plateau Rosa following the construction of the recent 3S Trockener Steg – Klein Matterhorn lift.
The new structure on the Swiss side will significantly affect access from that side. (Fig.2) Given the presence of summer skiing, there are no changes concerning skiers on the Italian side. In contrast, on the Swiss side, the passage is obligatory from the Klein Matterhorn, the only connection point for the descent to Trockener Steg first and with Zermatt later.
The opening of the new Swiss lift will affect the summer season because it will provide an access route to the ridges with views of the Matterhorn and Monte Rosa massifs, as is the case with the new Mont Blanc cableway.
