The border as shown by
Swisstopo separates the Swiss canton of
Valais from the Italian
Aosta Valley and
Piedmont region, the canton of
Ticino from Piedmont and
Lombardy, and the canton of
Grisons from Lombardy and
South Tyrol. Running east from Mont Dolent, the border touches
Grand Golliat and the
Great St Bernard Pass and then visits a series of
three-thousander peaks including
Mont Velan,
Mont Brulé and
Tête Blanche before rising to at
Dent d'Herens and to at
Matterhorn, followed by
Furgghorn,
Breithorn,
Zwillinge,
Monte Rosa at , and
Grenzgipfel just east of Dufourspitze at . The border now encircles the Italian
Domodossola valley, passing
Gonda,
Monte Leone,
Bortelhorn,
Helsenhorn, traversed by the
Simplon Tunnel connecting
Brig with
Varzo,
Grieshorn just south of
Nufenen Pass, and forming the western border of Ticino runs across
Marchhorn,
Basodino,
Pizzo Fiorera,
Wandfluhhorn,
Pizzo Quadro,
Pizzo di Porcaresc,
Pilone and descends below running across
Centovalli along a stretch of the
Melezza. It rises again to
Pilone peak before descending to
Lago Maggiore between
Brissago and
Cannobio, on the left bank making landfall at
Caviano and passing west of
Lugano and the villages of Malcantone to
Ponte Tresa at
Lake Lugano. It then forms the southernmost corner of Switzerland including
Chiasso, turning north again outside of
Como and now forming the eastern border of Ticino running west of
Lake Como, of passing Lake Lugano again east of Lugano and touching
Monte Boglia,
Cima di Fojorina,
Gazzirola,
Cima di Cugn,
Pizzo Campanile, again reaching at
Pizzo Quadro between
Val Mesolcina and
Chiavenna, and further north to
Pizzo Tambo,
Splügen Pass and
Piz Timun. The Swiss-Italian border here has the peculiarity of including the reservoir of
Lago di Lei in Italy but in an artificial salient including the reservoir's dam in Switzerland. Turning south again it traverses
Val Bregaglia at
Castasegna and turns east towards
Cima di Castello, now forming the northern border of the
Valtellina, a territory that was lost by the
Three Leagues in 1797 with the formation of the
Cisalpine Republic.
Val Poschiavo remains part of Grisons, and is separated from Valtellina by the border passing just north of
Tirano, turning north again along
Piz Paradisin,
Munt Cotschen,
Piz da l'Acqua to the inclusion of
Livigno in Italy. The border now follows the southern watershed of
Val Müstair, touching
Piz Murtaröl,
Piz Tea Fondada,
Piz Schumbraida,
Piz Umbrail until it reaches the pass road connecting
Vinschgau with the Valtellina and
Stilfserjoch. The border now turns north for a final stretch separating Val Müstair and the
Engadin from
Vinschgau,
South Tyrol, terminating at the Austrian-Swiss-Italian tripoint just north of
Piz Lad.
Campione d'Italia Campione d'Italia is a
comune of the
Province of Como in the
Lombardy region of
Italy and an
exclave surrounded by the
Swiss canton of
Ticino. At its closest, the exclave is less than from the rest of Italy, but the intervening mountainous terrain requires a journey by road of over to reach the nearest Italian town,
Lanzo d'Intelvi, and over to reach the city of
Como. The entire territory of the Italian village was
de facto included in the Swiss Customs Area as per a unilateral decision by the Swiss authorities. Being an exclave of Italy, it is not possible to reach the territory without crossing either Swiss territory or waters. On 1 January 2020, Campione and the Italian waters of
Lake Lugano became part of the
European Customs Union and a customs border crossing and check points were established. ==Transportation==
