My wife and I are traveling in mid-September. Can you tell me what the hours of operation are for the connection between Murren and Lauterbrunnen via the train to Grutschalp and the cable car down to the valley floor?
You can see the schedule at www.sbb.ch/en
There may be later hours using the bus to Stechelberg and the cable car to Muerren.
Use Murren BLM as your starting point and Lauterbrunnen BLM for your destination. This will take you via the train connecting in Grutschalp to gondola on down to Lauterbrunnen.
The Murren (Schilthornbahn) is the gondola down via Gimmelwald to Stechelberg and connecting to Post Bus to Lauterbrunnen.
Gondola from Murren begins at 5:55 with last gondola departing 23:45
Train from Murren begins 6:06 with last departure 22:55
