For the journey to the Jungfraujoch, we strongly recommend a paid seat reservation (CHF 10 per person). This reservation is valid for return journeys on the Jungfrau Railway from Eigergletscher / Kleine Scheidegg and ensures that you can travel at the desired time. Without a timed seat reservation, the Jungfrau Railway may well be full at peak times and you will have to wait for the next train. Book now at jungfrau.ch/seatreservation.
