Glacier tours allow hikers and mountaineers to explore high-altitude glacial landscapes under the supervision of certified mountain guides. Depending on the route and destination, these excursions range from introductory glacier walks designed for novices to demanding, multi-hour or multi-day high-alpine mountaineering expeditions. Across the mountain resorts in the dataset, glacier touring is predominantly practised during the summer season, while select destinations such as Cervinia and Silvaplana also operate activities across the spring and autumn months, and others like Fiesch, Pontresina, and Saas-Fee continue into autumn.
Several Alpine resorts offer distinct itineraries led by local mountain guides. In Fiesch, visitors can experience guided treks onto the Great Aletsch Glacier or view the area along the Aletsch Panorama Trail. Pontresina provides guided trekking on the Pers Glacier, a major tributary of the Morteratsch Glacier, which can also be accessed near St. Moritz. Saas-Fee caters to multiple experience levels, featuring beginner walks as well as advanced high-alpine expeditions. In Italy, Champoluc offers guided treks starting from Punta Indren toward the base of Castor and Pollux, whereas Cervinia provides specialized glacier trekking courses and high-altitude ice climbing. In France, Val Thorens features guided glacier hikes to Pointe du Bouchet, and Les Arcs organizes summer glacier outings within Vanoise National Park.
