Some apes, it seems, are more equal than others.
Enjoy a nice hike through various terrain. Keep an eye out for sentries as there is a watch tower and fenced compound near by.
You are looking for a 13lt plastic container. There are a number of swaps and prizes for 1st, 2nd and 3rd to find.
The Apes have enforced a curfew outside of the hours of 8am to 4pm during fire season. Make sure you leave plenty of time to escape before the curfew... otherwise you will be trapped within the forbidden zone.
