We halted only three days in Darmstadt, so we could only cover Interlaken. Th
e train trip to Jungfrau will take a whole day and the next day we spent in the Interlaken village, where you can spend time paragliding, shopping or taking shorter routes up Jungfrau. Because of our schedule, we had to change two or three trains to get there, but it was very convenient . There is an Indian restaurant on top of Jungfrau. Since it has been four years since we visited, I will have to slowly recollect the details. But you can see the following link to get some more information.
