In Chilean Patagonia, around 51 degrees south, is one of the most pristine areas on Earth outside of nearby (1000 miles away ) Antarctica. Though the mountain is only 9800 feet high , it is one of the most difficult on Earth to climb – due to steep grade and treacherous weather conditions most of the year. ArcticTropic has dozens of adventure travel and accommodation providers in Patagonia – both in Chile and Argentina.
