reserve in Cameroon
Dja Faunal Reserve, in the south-eastern part of Cameroon, is a UNESCO World Heritage Site.
There are many different animals, including monkeys, in the reserve. However, you probably won’t see them.
The road is rough and dirt. It might look a short way on the map, but it takes a while. Buses do go to the village just outside the reserve, or you could take a 4x4 vehicle. But, be wary during the rainy season, you could easily get stuck for days.
You are required to pay a park fee, hire a nature guard (he or she will have a gun), and probably a guide as well. Total should be around 10000 to 15000 CFA for all three.
You'll have to walk, there are no other transport options in the reserve.
Pygmy villages, you could pay to see a traditional dance.
There isn't much to buy, or many options. The locals may have something for you if asked.
Best to take your own food if picky. Some of the locals may cook for you if you ask (~3000 CFA).
Your two options are camping or staying in the village just outside the reserve.
It's best to go with a guide who knows the area and can advise on all the above. Contact a tour company (e.g. in Yaoundé).
