Get the first-hand experience of the jungle.
Experience jungle survival by using the least equipment possible (it might be limited to a machete, spear, rope for trapping), sleeping in hammock, eating from gathering (wild vegetables and fruits, bamboo, rattan or palm shoot) and hunting (snake, ell-fish, crabs, shrimps, lobster, frogs, insect) for at least 3 days according to demand (it could be month). We will trek along the river so the nature will help us to survive easier.
You can learn how to get food and water from the jungle and build a shelter.
