Hi

1. How does the following itinerary sound for a day in Murren? My base is Murren.

2. Also, I would like to know how many tickets do I purchase for the following:

3. Is this too much walking??

Start: Murren

1. Murren to Stechelberg Transportation

Stechelberg to Lauterbrunnen Hiking taking in the two falls Trummelback and Staubbach

2. Lauterbrunnen Transportation to Grustchalp

Grutschalp to Murren Hike

Thanks

Hi. This would be a fairly easy day. The walk from Grutschalp to Murren is about 1 hour 20 mins - similar time from Stechelberg to Lauterbrunnen - leaving plenty of time to divert to visit the two waterfalls. Enjoy!
