I was in Laax (Switzerland) for two nights and there is this canopy walkway that allows you to watch birds and other animals. It costs 22 Franks, which is ridiculous as you don’t get a tour or anything like that. But you can then spend the whole day there. It only took be a minute or so to see a crested tit. They are so close that the α6700 with the 70-350 mm lens were enough to take some nice photographs.
