I can attest that these photos are from Sweden. Specifically, the country's second largest city, Gothenburg. I can express myself even more precise and say that it is the little place Kåsjön. I know because I find spent eight summers there in my childehood. I remember that at that time was very strict rules about what you could do in the wild and what was forbidden. Times have certainly changed. The video on Youtube is from 2012.
