Switzerland and Italy currently tie for my favorite countries in the world. So far I have not seen scenery more beautiful than in the Bernese Oberlands in Switzerland. My favorite towns to visit are those in and around Interlaken, including Grindelwald and Lauterbrunnen. There is a very magnificent and powerful sensation being surrounded by mountains on all sides. The natural tendency is to want to ascend those mountains. Granted, my ascension occurs in the most pleasant way possible, via the impeccable Swiss train system.
The Jungfraujoch mountain station can be reached from a couple places, including Interlaken and Grindelwald. At over 11,000 feet in elevation, it is an experience not to be missed.
