Geneva Airport to Murren?

Yes, of course, people take that route all of the time. You can find all your connections at www.sbb.ch/en

Your beginning point will be Geneva airport and you destination will be Murren BLM

It will show you all of your connections, platforms, times all the way up to Murren. Just buy your ticket and jump on the next available train. You can get off along the way if you want and hop back on the next train.

The Golden Pass runs along that same route on the same tracks as every other train. It’s nice, but don’t waste your precious vacation time in Murren trying to wait for the golden pass train. Just get on any train going there.

Yes, I've done it many times, and it takes about 4 hours. Tim is right, just take the next available train. You'll still see the same sights.

As you leave the baggage area of Geneva airport, there is a machine that will give you a free 80 min transportation ticket for Geneva. If you exit the front doors of Geneva airport, on your left is a stairway to an underground mall and the train station. Take the 10 min ride to "Gare Cornavin" which is the next stop and the main train station for Geneva. There you will find a Migros grocery store with fast food to go and a travel office which will help you with your tickets. They speak great English and are very helpful. You just purchase a ticket that says something like "Geneve to Murren" and take any set of trains on that direct route. If figuring out times and tracks and next trains is daunting to you, just ask them to print out the times and tracks and they will gladly do it.

You will have to change trains in Bern, and then again in Interlaken OST (not West). There you will find the train to Lauterbrunnen (usually on track 1 or 2) that has smaller cars, which will say either "Grindelwald" or "Lauterbrunnen" on the side. That train will later separate, so make sure you are in the right cars. Confused? Just ask any conductor.

Once in Lauterbrunnen, cross the street (or take tunnel underneath) to the cable cars that go to Grutschalp. They time this so that the transfer is efficient (maybe 5 min) so don't loiter around the Laut. station. Once you are up at Grutschalp, there will be a train waiting for the 10 min ride to Murren.

Personally I would fly into Zurich instead. Take to the train to Luzern spend a few hours walking around, and from there hop on the Golden Pass to Interlaken and up to Murren. This segment of the Golden Pass route is much more scenic than the Montrex-Interlaken segment.

Great info! I should have added, we will be going the other direction on the way home as we fly out of Zurich, it otherwise felt like we’d be going back and forth from Zurich, so, we’ll get to pretty much cross Switzerland by train and see a nice chunk of the country.

Jared, standard bit of advice:
When travelling from Mürren to Zürich airport, the default route is the quickest, back to Bern (the way you came in when coming from Geneva), then the high speed line to Zürich.
A better if slower route is via Luzern. Between Interlaken and Luzern this is the Brünig Pass line, and is scenic.

And, when looking up trains, the station at Zürich airport is called Zürich Flughafen.

I know that before you've been there, the trip from Geneva to Muerren seems daunting, particularly the Interlaken to Muerren part, with all those changes, all those unfamiliar looking Swiss-German place names, and all those different modes of transport (train, rack railway, lift, etc). However, once you're actually on the ground doing it, it's very easy. The route from Interlaken to Muerren doesn't go through the mountains, but has to go up, down, or around them. Once you can actually see the mountains and valleys, it's quite straightforward. Plus, all the transit is coordinated; when you get off one, the next one is usually waiting. Plus plus, everyone is going the same way, so you can just follow the crowds.

As mentioned, all routes in Switzerland run at least once an hour, and on this route things run 2-4 times an hour. And the transport on this route is unreserved. So, if you "miss" a connection because you stopped to use the bathroom, buy a snack, etc, just get on the next one.

The Golden Pass route is actually a longer route with several segments. The most scenic and famous portion of that is between Montreux and Zweisimmen, which is not along the fastest route from Geneva to Interlaken. (To plan a detour, add both those towns as "via" or "stopover" midpoints on a train schedule search). Of course, the view on your later trip from Interlaken to Luzern is also part of it and also lovely.
