Most international visitors will make a stop in Luzern. The city offers the old Kapellbrücke as well as old buildings, murals, houses, souvenirs shops, a stone lion and lots more. Just around the corner are the Vierwaldtstättersee (aka Lake Lucerne) and the mountains with Rigi, Pilatus and Titlis the best known.
Geneva is probably the most international city in Switzerland: several global organisations (e.g. United Nations, World Trade Organisation & Red Cross) and corporations have their head quarters here. For tourists the Jet d´Eau ("water fountain"), the many quality watch stores, the large Lake and the vicinity to France are most obvious.

Interlaken is located in the heart of the Bernese Alps Interlaken is very well visited by tourists. And with good reason. The vicinity to the mountains, the abundance of activities, the unique location between Lake Thun and Lake Brienz and the excellent shopping make this a place well worth visiting. From here it is a short trip to Grindelwald or Lauterbrunnen for more scenery, waterfalls and the Jungfraujoch.
Very few cars are allowed in this village in the Swiss Valais-region. Only for the better! It is nice to stroll and admire the buildings or have a drink. Worldfamous - ofcourse - is Zermatt´s house mountain: the Matterhorn. Indeed it is picturesque. You can view it safely from the Gornergratt or climb it with a guide, but be aware that others tried as well and some ended up in the local grave yard....
Bern is the capital and political center of Switzerland. Furthermore it is a beautiful place both for visitors and residents. The old city is preserved and listed on UNESCO. Don´t miss the clock tower around noon, the cathedral or the bears in their bear park. Or just enjoy watching a game of chess in front of the government building with kids splashing in the fountains...
Montreux is located at the east end of Lake Geneva and just West of the Bernese Alps. Chillon Castle and Charles Chaplin's museum can be found here. Once a year there is the world famous jazz festival. Yes, there is lots to do.
