My suggestion to eloping in Patagonia are:
TORRES DEL PAINE NATIONAL PARK
LOS GLACIARES NATIONAL PARK
EL CALAFATE
PATAGONIA LAKES DISTRICT

It depends! Because Patagonia is technically Argentina & Chile, each will have their own rules, regulations, and requirements.

On the southern tip of the continent of South America lies the region of Patagonia. It spans two countries—Chile and Argentina—and includes the pampas regions, the fjords, the southern Andes mountains, and the coasts of the Atlantic & Pacific. Because the region is South of the equator, the seasons are flipped, which means summertime is December-March.

Windy cliffsides overlooking epic glaciers, turquoise blue alpine lakes, the most toothy and prominent mountain peaks you’ve ever seen. In terms of places to get married, it’s probably one of the most wildly beautiful landscapes you could imagine. Most places here require a bit of hiking to get to, and some decent gear to shield from the ever-changing weather and wind in the region.

This area of the world has completely stolen our hearts. Patagonia embodies everything we love about adventure — the wild wind and jarring landscapes, the tiny towns and unique food, the moody weather and feeling of awe you experience when standing below a towering mountain like Fitz Roy or Cerro Torre or the Torres del Paine.

Of course I am not. There is a lot of photographers doing elopement weddings in Patagonia. The good thing about me is that I am based in Chile so my travel feed are much lower and I am about 2 hours from Punta Arenas. I speak Spanish, English & Polish and I know the Chile culture very well, that said, I am the right local Patagonia wedding photographer for you.
