So just what is making everyone so happy in Switzerland?
Here’s our list to just some of the unique sights, stunning scenery, great things to do, fun events and special experiences that might have a little something to do with why everyone is feeling the love.
On the border between lower and upper Engadine, Zernez is the main gateway to the Swiss National Park.
Begin with a visit to the Park House, where you can get all the information you need and also watch an audiovisual presentation on the park.
The park itself is small (160 sq km/ 100 sq miles) and very well preserved: you could forget about the human race here, if not for the signs indicating (very clearly) the paths for forest walks.
The best time to visit is from mid-June to the end of October, when the Park House is open.
The flora is particularly varied because of the very hilly terrain, and you may catch a glimpse of such unusual animals as ibex, elk, marmots and vultures.
During the Reformation, the towns of the region converted to Protestantism, but Müstair, barricaded behind the walls of its monastery, remained Catholic.
The big attraction here is the Carolingian convent of St John the Baptist, dating from the 8th century; it contains the best-preserved and most extensive collection of Carolingian wall paintings in the Alps.
The convent is closed to the public but the church opens daily 8am–7pm, and a museum with guided tours tells the history of the convent.
The high valley of the Engadin with its wonderfully varied network of trails – 580 kilometres (360 miles) in all – is heaven for hiking.
The contrasts that characterise this region are bewitching: gently sloping hills draped with lush alpine meadows stand close by mighty glaciers, towering snow-capped peaks and sparkling lakes.
The best way to explore this unspoilt landscape is on foot – whether hiking along one of the breathtaking panoramic trails or one of the fascinating theme trails, on a walk along the sparkling lakes, or on a multi-day trek.
The comprehensive network of trails also includes pushchair-accessible paths that are particularly suitable for families. Those preferring a more ambitious mountain hike can make for one of the four areas served by the mountain railways and cableways: Corviglia/Piz Nair, Corvatsch/Furtschellas, Diavolezza and Muottas Muragl/Alp Languard.
These all offer thrilling high-altitude trails with spectacular views.
The upper Engadin provides wonderful wind conditions at high Alpine altitude of 1800 metres above sea level.
Here in Engadin wind and water works wonders: the lakes set windsurfers pulses racing.
As soon as the Maloja wind sets in around noon, the colourful kites start to bob and dance across Lake Silvaplana. The quickest and most effective way of learning the correct technique is by booking a few lessons at the Swiss Kitesurf School in Silvaplana.
The school was the first of its kind in the world – after all, this trend sport was invented here at Lake Silvaplana – and can in the meantime look back on 18 years of experience.
