dag,
It sounds like you have the transportation from Paris to Lausanne worked out, so I won't comment on that. However a few other questions.....
- where are you planning to stay in Lausanne? The town is on the side of the hill so it's a good idea to consider the location for ease in getting around. There is a Metro (Funicular) that runs up and down the hill, and that's a big help.
- are you planning to take any day trips while in Lausanne?
The trip from Lausanne to Mürren is very easy, about 3H:08M with four changes, depending on which trains you use. You can look at all the solutions on the bahn.de website and it's very easy to buy tickets at the station in Lausanne.
Using the 10:50 departure from Lausanne as an example, there are changes in Bern, Interlaken Ost, Lauterbrunnen and Grütschalp (that sounds rather convoluted but it's actually very easy). Here's the route you'll follow using the 10:50 departure......
When you buy your tickets, be sure to specify Mürren BLM, as there are two routes to Mürren from Lauterbrunnen.
- 10:50 depart Lausanne
- 11:56 arrive Bern
- 12:04 depart Bern
- 12:57 arrive Interlaken Ost (note that there are two stations in Interlaken and Ost will be the second stop).
- 13:05 depart Interlaken Ost on the Berner Oberlandbahn which will probably be waiting. Be sure to check the digital display on the side of the coach to ensure that the destination for that coach will be Lauterbrunnen (some trains split at Zweilütschinen).
- 13:25 arrive Lauterbrunnen. When you get off the train, walk across the street to the Cable Car station, walk up the stairs and board the cable car which will probably be waiting.
- 13:38 depart Lauterbrunnen
- 13:42 arrive Grütschalp. When you arrive there, the small mountain railway will be waiting. Get aboard and enjoy the scenery on the way.
- 13:58 arrive Mürren. You'll arrive in the lower level of the station and you can either exit there or walk up the stairs and exit through the lobby of the station. You'll be at one end of town so there may be a short walk to your hotel. The Schilthornbahn is at the other end of town.
Schedules may change although not likely, but it would still be prudent to check again before your trip.
You may find it helpful to buy one of the Swiss passes to minimize the cost of transportation, as it can be expensive especially if you're using a lot of the mountain lifts.
The trip from Mürren to Munich is also fairly straightforward. One of the quickest and cheapest trips will be a departure from Mürren at 08:06, arriving 14:59 (time 6H:53M, 5 changes, final segment via Bus from Zürich). If you decide on that option, it's not too difficult.
When you arrive at Zürich Hbf, you'll need to walk to the Carpark Sihlquai to connect with the Bus (400 M). As I recall that's an easy walk from the station. If my memory is correct, these are the details....
- With your back to the tracks and looking towards the front of the station exit on the left of the building on Museumstrasse.
- Walk towards the Walhalla Hotel which should be visible when you exit the station. The Carpark Sihlquai is right across from the main entrance to the hotel, around the corner from the part of the hotel that faces the station. You can't miss it as there will probably be lots of tour Buses in the lot.
- it's only about a five minute walk from the station to the hotel, so it will be about the same to the Carpark.
Gueti Reis!
