Train ride in Switzerland alps

Do the following as a round trip

• Train 1: Zürich - Luzern
• Train 2: Luzern - Brünig Pass - Meiringen - Interlaken. This is the scenic leg.
• Train 3: Interlaken - Bern - Zürich (you may also have to change trains in Bern)

All these trains are at least once per hour. You can stop off at any stop and catch another train one hour later.

@Chris F, question about the Luzern to Interlaken train. You say this is the "scenic leg" - if we are taking the train from Geneva to Bern, staying the night, then going up to Murren for 2 days, is it worth taking the one-hour longer Murren to Zurich via Luzern route, as opposed to the Murren to Zurich via Bern route? I guess what I'm trying to say is, do you think the 2 days we are spending high up in the Alps is the best "scenery" we are going to see, and will we find the longer route to Zurich as "more of the same" so we would do better by taking the one-hour shorter train ride via Bern?

Fredandkell, the route via Bern goes through industrial areas. The longer route via Brunig to Luzern is gorgeous in a different way from Mürren. The Brunig route passes blue-green mountain lakes and quaint chalets all along the way to Luzern.

fredandkell, yes, if going from Mürren to Zürich, and you have the time to spare, it is worth the extra hour to go via Luzern instead of via Bern. It is a very scenic route.
And you will already done the Bern - Mürren leg when you arrived.

I would not call the route via Bern "industrial", but it does go through the Swiss Plain between Bern and Zürich. The Luzern route is actually shorter, but it takes longer because it goes "over the top" instead of around.

Also, the route via Luzern is a couple of Francs cheaper. Sorry, less expensive. "Cheap" is not a word in Switzerland.

Thanks, guys! I'm not worried about cost because we will have a Swiss pass. I was just wondering if the extra hour is worth it since we will have already seen a lot of beautiful scenery by staying up in the Alps. (We'll be with an 8-year old and 11-year old.) Sounds like the answer is "yes."

The Bern-Interlaken train ride is nothing to sneeze at, passes by many pretty lakes and follows a river and gets mountainous as you go along
