Found The Siren Head Tower

I found the Siren Head Tower from the Chapter 1 movie, it's a public observation tower in a place called "Parc régional du Mont Morissette" in Blue Sea Quebec! The park has hiking trails which is where the forest part of the movie was filmed. I'm not sure where the Airbnb cabin is though, I think there's cabins in or around the park so it's probably one of those!
