Hello Zach
As many others here I recommend Argentina and/or Chile.
August is snow high season in both countries and The Andes are a perfect landscape for what you’re looking for. As well as Ushuaia, the southernmost city in the world.
Our company has a big experience in this kind of projects, you can check our portfolio in our website. http://www.mondocine.com
