Davos in Grisons is a place of superlatives: this holiday destination with international ambience is the largest resort in the Alps for mountain holidays, sport and conferences, at 1560 m the highest town in the Alps and a high-altitude health resort with a long tradition.
Sion, called Sitten in German, is the capital of the Canton of Valais. The Old Town, which lies between the hills of Valère and Tourbillon, dates back to the Middle Ages and is home to numerous sights and attractions, such as one of the world's oldest organs that can still be played.
The mild climate at Lago Maggiore is unique in Switzerland, and enables subtropical plants to flourish in the open air on Isola Grande, the large island. The Botanical Gardens of the Canton of Ticino house around 1,700 plant species.
