Wo in der Schweiz ist das?

I _think_ the lakes at the start are the Fessis-Seeli and the ridge at 0:03 is the ridge from Gufelstock to Heustock. But not 100% certain.

I think it’s uhm Aletsch

EDIT:Yes it is Aletsch after fully watching the video, I think I’ve been there, saw the bridge where I fell

EDIT 2: Actually Im nit sure anymore. But Aletsch has a lake just like it but Im sure it’s in Kanton Wallis
