Please advise on 6D 5N

Hi, my wife and I will visit Switzerland on 7 Oct 2014 for 5 Nights.
There are few questions I would like to seek your advise for it.

Day 1: Arrived in Geneva airport around 09:00. Take a train to Lauterbrunnen and stayed for 3 Nights. Visit the Trümmelbach Falls and Wengen (by train)

Day 2: Take a train from Lauterbrunnen to Wengen and then take a cable car to Mannlichen Mountain. Rather than return back to Wengen by Cable car, we plan to walk through the mountains to
the village of Kleine Scheidegg. From Kleine Sceidegg, take a train back to Lauterbrunnen

Day 3: Visit Jungfraujoch by train. After visit, take a train to Kleine Sceidegg and walk to Wengen. From Wengen take a train back to Lauterbrunnen

Day 4: Any advise?

Day 5: Geneva

Day 6: Geneva: take an early train to Paris

Could you please advise us which travel pass suitable for us as well?

Thank you

Hi ymchay, welcome to the website!

For day 4, you can find suggestions for local activities in the Jungfrau region here, or in a wider region here. You can do one more local hike, a boat trip, or a combination. There are many, many options. Be sure to check the weather every day and adjust your plans if needed.

A Swiss Card would be a good option for you. It included the trip from the airport to Lauterbrunnen and back for free, and a 50% discount on the trip you will make during your stay. Validity ends after the return trip, so you can't use it in Geneva, but you will get free public transport there anyway if you book an hotel in town.
