We would be staying in interlaken in july 2012 and have only 3 nights on us.
Here;s the itenerrary i have planned. PLease suggest your views.
Day 1- Arrival in Interlaken at Noon time. See interlaken by walk. If possible then we would like to take lake brienz or lake thun trip. ( do they take whole day ).If its not possibe on the same day, we will move it to next day.
Day 2- Lake breinz or lake thun trip, and then upto lauterbrunnen, wengen and murren. ( are all 3 possible in one day )
Day 3 - Grindelwald.
Im not perfect at this, therefore all your suggestions are welcome.
