Switzerland is also known in Latin as Confoederatio Helvetica. That is why their internet domain is .CH. You will need to use the Swiss Franc (CHF) when in Switzerland.
Flying to Switzerland
If you are flying from the USA, you would probably fly into either Geneva (373.6 m – French speaking area of Switzerland) or Zurich (408 m -German speaking area of Switzerland). Basel Airport ( EuroAirport Basel-Mulhouse-Freiburg ) is also an option but it is actually located in France. Basel EuroAirport serves Germany, France and Switzerland.
Take your time in these lower elevations to acclimate to the altitude. You should drink plenty of water as you recover from your flight especially if you are flying across the Atlantic from the USA.
From any of those cities, you will need to get a train to Interlaken ( the city between lakes Brienz and Thun at 566m). Interlaken is a good base to explore the Lauterbrunnen Valley and the Bernese Oberland. The train system is excellent in Switzerland and runs on time like Swiss clockwork.
Bernese Oberland and the Lauterbrunnen Valley
There is so much to see in the Bernese Oberland (Bernese Highlands) area. You can use Interlaken as a base camp to travel further south in the Lauterbrunnen Valley. Interlaken has all the modern conveniences you need. If you are not into too much walking, just ride the train from Interlaken Ost Station to Jungfraujoch. Jungfraujoch (Virgin Pass) is the highest railway station in Europe or Top of Europe. You will be going up in elevation from 566 meters in Interlaken to 3454 meters in Jungfraujoch.
There is more than one way to get to Jungfraujoch. You can take the train from Interlaken (566m), Zweilütschinen (652m), Lauterbrunnen (795m), Wengen (1274m) (car free), Kleine Scheidegg (2061m) (beautiful place to stop) and then on to Jungfraujoch (3454m). The other option is to take the train from Interlaken, Zweilütschinen, Grindelwald (at 1034m another very beautiful place), Kleine Scheidegg and on to Jungfraujoch. Take one way up and another way down as the journey can be the destination on this route. You will pass through Alpine scenery and then on to see the snowy peaks above timber line. Jungfrau stands at 13,642ft or 4158m. Jungfrau, Eiger (3967m) and Monch (4107m) peaks form a massive range overlooking the Lauterbrunnen valley.
The Lauterbrunnen Valley
The Lauterbrunnen Valley is a must see area of Switzerland. The contrast between the snowy peaks with the green Lauterbrunnen valley with many waterfalls is a site to see. The picturesque Lauterbrunnen village with the 300m high Staubbach Falls cascading down the mountain is breathtaking.
From Lauterbrunnen, you can take the cogwheel train to Wengen (car free) to get a gorgeous view of the Lauterbrunnen Valley. Take time and smell the mountain air and soak in the Alpine scenery. Beautiful view of the Lauterbrunnen Valley for your photos for instagram.
Or from Lauterbrunnen, take a cable car to Grütschalp and then by mountain rail to Murren. Then hike downhill to Gimmelwald Village to go back in time. Enjoy the alpine scenery, the flowers and breathe in the fresh mountain air. It is well worth it. There is even a gondola that goes to Schilthorn from Gimmelwald for more exploration. The options seem endless. You can be lost in the Bernese Oberland and loving it.
