The Jungfrau is one of the tallest peaks in the Swiss Alps and the highest point in Europe accessible by train. At the top there are a few restaurants, and you can enjoy skiing, tubing, ziplining, and — of course — amazing views. When I visited in October, it was chilly at the top but fortunately we had a sunny day. Both the tubing and zipline runs were quite crowded.
