4 travelers. 4 months. No support team. A documentary following an adventure into Patagonia for exploration and conservation.
Garrett Martin launched a Kickstarter campaign to raise $15,000 for an adventure-travel documentary on the longest continual trail network in South America.
They started December 22nd, 2016 on a 4-month journey through Chile.
I’m planning on returning myself to section hike parts of the Greater Patagonian Trail January 2018.
