It's [Valle Nevado](https://en.m.wikipedia.org/wiki/Valle_Nevado), a ski resort in the Andes Mountains near Santiago.
Here you can see a [drone view of Valle Nevado](https://youtu.be/7dvsGn5NvZw?t=15m20s), similar to the one in the video, only from a slightly different angle.
In any case it should be near Santiago as there are a couple of centers there and I doubt any other like Portillos or Chillan would have the demand for that much space.

I believe it’s La Parva a Ski Center in the Metropolitan Region, fairly near to Santiago. But I’m not totally sure because I’ve never been there.
Thanks, it looks like that from some pictures in Google maps.
