I will be in Wengen for 5 days in July. I would like to spend one day around Lake Brienz and I like to know how to plan it to be a pleasant day trip. Can I take a train with scenic views there? which steamer cruise to take? I heard the lakeside villages are really quaint and if I plan my trip so I end up at the stop at the Geissbach Falls/hotel around lunch time it can be a nice treat. Is visiting Ballenberg museum a good idea? I will have a 1/2 fare travel card.
