I backpacked around Europe for six weeks last year with a friend, and Gryon was by far our favourite place. Even if you plan on staying there a day, you will stay for a week.
The main reasons people come to Zermatt are for the Matterhorn and the skiing. There are great views of the Matterhorn and other mountains from the town (and better views from Kleine Matterhorn and Gornergrat) and most of the skiing is in the difficult range.
I stayed in Fribourg, Switzerland in August 1990. It was a quiet, peaceful, and lovely place then.
Lausanne is a beautiful city, filled with young people, mostly university students. I definitely recommend going there, and the nightlife is fun as well.
OMG Gimmelwald Switzerland is the most beautiful place I have ever been.
Geneva is nice but very upscale. Definitely take the train around the lake to nearby Leysin and stay at the Hiking Sheep. If you get there for a summer celebration, you can watch the fireworks from a cliff looking over the lake.
I will always have Lucerne in my heart.
Go out on the Marktgasse. Bars close early, so start early. Clubs can be located within reach. Zurich is a great city, enjoy it and be respectful.
Kandersteg is my favorite village in Switzerland. It is less crowded than Interlaken and seems less commercial. Mountains are close and there are many hiking trails with great views. The tourist office can suggest hikes and/or tell you about earning a gold, silver, or bronze hiking pin by completing six for each level.
I've visited Lauterbrunnen twice and am captivated by this town and its amazing setting. One of my top five favorite natural setting in the world. In the fall the constant sound of the many waterfalls was very serene. In the winter this place was even more beautiful. The second time without the rain I was able to …
Switzerland is a place that is not to be missed. Absolutely one of the most beautiful on the planet. Interlaken is the town to visit as most others are boring shopping malls. This place has everything for a really nice rest in between big cities as well as some of the most amazing outdoor activites you could imagine.
Bern is fun to walk around in, there are lots of cute fountains, but the Bear Pits are slightly depressing. I liked the art museum, but after one day I thought that I had seen most of the city.
