Italy borders the Swiss tourist regions of Graubünden, Valais and Ticino to the south. Many activities are carried out or organized across borders. This is especially true of the ski resorts in Valais. The Matterhorn Glacier Paradise is a well-known example of this. With the Testa Grigia railroad station, the connection of the Theodul Glacier area to Italy was completed. The nearby Milan airport is connected to the Swiss tourist areas via transfers.
