Patagonia is one of the places I miss the most. The great outdoors divided between Chile and Argentina has so much to offer for lover of nature. Finishing your trip in Patagonia is great since you got time to acclimatize to altitude in countries like Bolivia and Peru. although the altitudes aren’t that high, the treks are hard and you need to carry you tents and food around when leaving for a few days. This place is more about having good leg endurance and wind resistance; the mountains often create wind corridors that will have you walking against 75 km/h winds.
