The ski area covers five separate mountains: It previously included Winterhorn, in Hospental, which was abandoned in 2007.

Train services (run by the Matterhorn Gotthard Bahn) are vital in this resort as they are the only means of transport available to travel from Andermatt (Nätschen and Gemsstock) to Oberalp, Dieni, and Sedrun.

It has 24 runs (39 km (24 mi) of pistes) and 5 lifts, and is located north of Andermatt.

[4] Nätschen generally closes early for the summer, as it is south facing and is quite low.

Sedrun / Oberalp is located near Dieni, and is the biggest of all of the three mountains' ski areas.

In Sedrun there are two small beginner runs, served by two T-bars and a magic carpet.
