The trip to Jungfraujoch on Tuesday is optional. Enjoy an exciting journey to the highest railway station in Europe – Jungfraujoch at 3,454 meters, with a breathtaking stop at the Eismeer station. Visir the Ice Place, which includes several sculptures of an eagle, penguin, or bear, as though they had just turned to ice, which appears very natural. Enhance your experience on the Sphinx Tower - the highest observatory in the world, from where you can look around 360 degrees at the neighboring countries and the longest glacier in the Alps, the Aletsch Glacier. A minimum of four travelers is required to confirm any optional tour. If the weather is sunny, it is definitely worth considering. However, Tuesday's standard itinerary already includes visits to the Lauterbrunnen Valley, the Aareschlucht Gorge, and the Sherlock Holmes Falls, so you will have a difficult choice. So, for Tuesday, group tour participants have the following options: 1. Visit the Lauterbrunnen Valley, the Aareschlucht Gorge, etc 2. Visit the Jungfrau on your own, while the rest of the tour participants visit the Lauterbrunnen Valley, the Aareschlucht Gorge, and the Sherlock Holmes Falls with a guide. 3. If all group tour participants wish to go to the Jungfrau, we will arrange the guided Day Tour with transfers from the hotel, train tickets to the Jungfraujoch and back for the entire group for CHF 300 for adults. However, in this case, all group tour participants will miss the trip to the Lauterbrunnen Valley, the Aareschlucht Gorge, etc. If you arrive in Zurich on Saturday, you could also visit Jungfraujoch independently on Sunday, before the tour officially begins. Depending on weather conditions and the number of interested travelers, we will be happy to discuss and confirm all details for the optional excursions at the beginning of the tour in Switzerland. You don't need to book optional tours in advance.
