The trip up to Jungfraujoch—top of Europe—is indeed a once in a lifetime experience. From Grindelwald the Wengenralp Railway (Switzerland’s longest cogwheel rail route) takes you along the North Face of the Eiger up to Kleine Scheidegg. There you change trains into the Jungfrau Railway and await transportation to Europe’s highest altitude railway station, Jungfraujoch. Along the way the train journey makes two stops at viewing platforms. The first gives you a fantastic view down to Grindelwald while the second stop offers a view of an awesome ice and snow landscape.
Once you’ve reached the Jungfraujoch, a variety of activities await you. Relax in one of the restaurants, soak up the views from the viewing platforms, or take the elevator to the Sphinx offering a 360-degree panorama of the Alps including the Aletsch Galcier (the longest Glacier in the Alps). For those who like to be a bit more active you can go Husky Sledging, hike to the Moenchjochs hut (approximately 1 hour each way), check out the ski and snowboard park or take a ride on a zip-line. Remember, you are at over 11,000 feet up here and it is cold all year long so dress warmly and wear appropriate shoes. We saw many people wearing hats and scarves and sandals!!
If you still have some time and energy left, get out at one of the half-way stops after Kleine Scheidegg and walk the rest of the way to Grindelwald or Wengen. It makes for a full day of adventure.
