Jungfraujoch is one of the most popular places to visit in Switzerland and I think one of the most expensive ones! Take a ride up to the top on the infamous Jungfrau Railway and experience the journey through the mountain tunnel with spectacular views of the glacier world outside. Once at the top, you can marvel at the wonders of the Alpine environment such as the Ice Palace, Sphinx viewing platform, walks in the eternal snow, and more. It's a once-in-a-lifetime experiences exploring Europe’s highest-altitude railway station.
