It will get you from Zurich or Geneva to the Interlaken area and back. It may be quite different high in the mountains than it is down in Interlaken.

One of the most spectacular is the Staubbach Falls at the edge of the village. From there you take another train up to Kleine Scheidegg and change again to a private railway. This train travels through a tunnel carved inside the north face of the Eiger in 1912. Halfway up, the train stops at a little observation window looking out onto the Eiger's nearly vertical face. At the top, it is a world of eternal snow and ice with a view on a clear day that can stretch all the way to the borders of Switzerland.
