The two parallel aerial trams join Lenzerheide and Arosa, two adjacent resorts that were previously unlinked.
Spanning a valley over a distance of 1.7 kilometres between the Hörnli and Urdenfüggli, the 150-person trams bring together two resorts to create a sprawling area with 225 kilometres of pistes.
“We are overjoyed and are very pleased,” said Philip Hollenstein, CEO of Arosa Lifts AG as the 50-million-franc ($55 million) lift was inaugurated on Saturday.
“The long-awaited dream comes true today.” Hollenstein said.
Lenzerheide has built two detachable six-seat chairlifts to create further links between two valleys and an area of sunny slopes dotted with mountain restaurants and huts.
“Unforgettable runs, unique peak experiences and culinary delights are guaranteed with this diversity,” Thomas Hunziker, CEO of Lenzerheiden Bergbahnen AG, was quoted as saying by 20 Minuten newspaper.
The resort introduced a new single ticket for the two resorts that costs 69 francs, including transport from Chur, and is valid for 42 lifts.
The two resorts have long remained in the shadow of their more famous neighbours Saint Moritz to the south and Davos-Klosters to the northeast.
But that is changing.
Swiss tennis star Roger Federer is among the celebrities attracted to the area.
The 16-time Grand Slam champion bought property in Valbella, near Lenzerheide, where he is building a twin chalet at a reported cost of around 17 million francs ($18.7 million).
