Zermatt offers year-round skiing, thanks to the surrounding glaciers having a ski terrain between 2500 - 3900 metres and Switzerland's highest vertical drop. The world's highest 3S cableway opened in 2019 transports the skiers to the Matterhorn Glacier at 3,883 meters altitude, where you can ski year-round. One of the best ski experiences in the Alps is skiing over the Theodul Pass from the top to down into the Italian ski resort of Cervina. Other activities in winter are heli-skiing, high-altitude ski-tours, Nordic trails, and night skiing. To enjoy winter sports here it is not mandatory to ski, there are other activities like natural ice-skating rinks, snowshoe trails, and multiple curling rinks.
