If you don't normally think of palm trees in Switzerland, you haven't seen the Ticino. Also called the Tessin, it's the Swiss Riviera -- the retirement fantasy of thousands of Swiss living in the northern cantons. Although Italian is the major language, German and French (as well as English) are also widely spoken.

A visitor could spend at least 2 weeks just touring the valleys of the Ticino. Officially, the canton begins at Airolo (the southern exit of the St. Gotthard Tunnel), but most visitors head for the district's major resorts of Locarno, Lugano, and fast-rising Ascona. Lugano and Locarno share the shores of lakes Lugano and Maggiore with Italy. Relations between Switzerland and Italy, however, weren't always peaceful. The Ticino was basically carved out of the Duchy of Milan by Swiss soldiers and staunchly defended in several bloody battles.

The name of the canton is taken from the Ticino River, a tributary of northern Italy's Po River. The balmy climate produces subtropical vegetation, which thrives in gardens famous throughout Switzerland. The district's weather is almost addictive between March and November, but the rest of the year can be cold and damp.

The proximity of Italy manifests itself in the Ticino's architecture and cuisine. Many buildings are made of stone and are proportioned like structures in Lombardy or Tuscany. Also, in many cases, a trattoria will be owned by a Swiss-German husband and a Swiss-Italian wife, so their cuisine ends up being a concession to each other's culinary traditions.

Sometimes getting to the Ticino is part of the fun. One of the most dramatic ways to arrive is over the Simplon Pass, a journey that stretches from the German-speaking town of Brig in Switzerland and, after crossing the pass, descends to the Italian border town of Domodossola, a distance of some 64km (40 miles). The pass owes its origins to Napoleon, who demanded a low-altitude pass 1,950m (6,396 ft.) above sea level through which artillery could be transported. This pass is often closed between December and early May because of bad road conditions. At those times, automobiles are transported on flatbed trains, which are carried through one of the longest railway tunnels in the world, the Simplon Tunnel. The tunnel stretches for 20km (12 miles). When the pass is open, it affords one of the most panoramic mountain views in Europe.

Rail passengers can also arrive dramatically by taking the Bernina Express, a 4-hour trip that begins in Chur and ends in Tirano, Italy. As you near the town of Chur, you will be awed by the rugged peaks around you, but before the end of the journey, as you near the Italian border town of Tirano, you'll see palm-lined lakefronts. This is the only express train that crosses the Alps with no tunnels, and, as such, it is one of the steepest railway lines in the world. At Tirano, the end of the rail run from Zurich, you can make easy bus connections on to Lugano.
