Can you imagine living over 100 feet up in the trees? A people known as the Korowai tribe don’t need to stretch their imagination at all because their lives have always been spent living in tree houses that soar high above. On the island of New Guinea in the southeastern part of Papua, the isolated tribe is the only group of people in the world that have established their primary residence in tree houses.

It’s an intriguing way to live that, to us, appears like a daredevil’s lifestyle, though the reason behind the elevated homes in the jungle is actually for safety precautions. The area, which is prone to flooding and populated with buzzing insects, proves to be a life-threatening and troublesome land to live on ground-level. As a result, the tribe uses labor-intensive measures to create each of their high-rise wooden homes atop trees.

As if creating homes on trees and managing to survive in them wasn’t enough, the tribe’s diligent process is yet another factor to be in awe of. There are no cranes or load-bearing machines to assist these men and women. Everything is done by hand. Even the few tools they use seem almost like they’re straight out of the Stone Age.

Today, most of the indigenous Korowai live in villages along the two main rivers in the west and east of the Korowai territory. Life there remains very simple and the Korowai are largely self-sufficient. However, in the villages they do have access to a rudimentary supply of modern foods (mainly rice, sugar and coffee) and medicines. As a result, these villages are attractive and are drawing more and more Korowai out of the forest.
