Oh no, it's I can confirm it is not AI-generated: I have been to this place several times !

It would be the "lacs de fenêtre", somewhere near the Grand-Saint Bernard Pass, at the border of Italy and Switzerland. The mountains in front are all parts of the Mont-Blanc massif. The hike is "easy" if you start from La foully and not from the pass ;)

This specific spot is often used by commercials, in switzerland you often get to see this picture (of this specific landscape). I am pretty sure the swiss national railway (SBB) used it a few months ago.
