The Jungfraujoch is as high as you can get by train, and certainly one of Switzerland’s best known mountain destinations. The top station is 3471 metres asl and is said to be Europe’s highest train station. The stop is not actually on a peak but rather on a pass in between the famous mountains Jungfrau and Mönch, both towering over 4000 metres asl. Up here, there is a path through the snow you can take and several viewing platforms, a lift takes you up to the top one called sphinx. From there you have a heart-stopping view over the Aletsch glacier, probably the most impressive glacier of the Alps. In the 1930s mountaineers began to cut tunnels and halls into the eternal ice - the so-called Eispalast was born, which now extends over 1000sqm. You certainly should take a walk through it. Many consider a visit to Switzerland incomplete without a visit to the Jungfraujoch. The ride up there is impressive too - and quite expensive. From Zurich, take a train to Interlaken (change at Bern), then one to Lauterbrunnen, from there another one to Kleine Scheidegg, where you board the final cogwheel train that takes you up to the top (mostly through tunnels, but with spectacular views at the stop Eigergletscher). Duration from Zurich 4:20.
