WOW. Now this is definitely worth seeing. These are beautiful waterfalls that are located in the mountains and over look the lake. The hike up is kind of steep but SO worth it to at least go to the bridge, that goes underneath the waterfall. The views of the lake and the hotel is stunning. There is a hotel Grandhotel Giessbach, which does look amazing to stay at. If you going to do an extra night around interlaken—might be worth doing a night here .
