To visit these shy endangered Mountain Gorillas in the Jungle you must buy a permit which costs $700 USD per person in Uganda and $1500 USD per person in Rwanda and always this money is paid in advance to book for your permit, if you are to visit both Uganda and Rwanda you have to apply for a multiple Visa which costs $100 USD per person, lastly you must be with a valid yellow fever vaccination Card to be issued entry permission.
Packing List for Gorilla photo Safari in Uganda & Rwanda.
Cameras:
Decent quality digital SLR are the best tool for the job in most mountain gorilla photo Safaris. If you are lucky enough to own a full frame SLR then this is best due to the higher performance in low light situations that you are likely to find yourself in. However, that is not to say that a cropped sensor will not do a decent job for you.
It is worth noting that on a cropped sensor SLR your zoom lenses will be extended depending on the size of the sensor. A 1.6x sensor for example will multiply the focal length of your lenses by that factor, this can be especially useful for other parts of your safari, and for example, a 200mm lens on a 1.6 x sensor would be equivalent to a 320mm zoom (200 x 1.6 = 320.
Lenses:
When selecting lenses many people elect for long telephoto zooms when traveling on safari. While these are often the best tool for the job when you are in some places like Bwindi Impenetrable National Park, they can be a bit too much when visiting the mountain gorillas. The reason for this is that, ideally, you should be around 7 meters from the gorillas, which is significantly closer than you are likely to be to a leopard in a tree.
If somebody else was paying for it (and carrying it, I would love to go with 2 x Canon 1dx bodies fitted with Canon EOS battery grips, a medium telephoto such as a Canon EF 24-70mm f/2.8L II USM coupled with a Canon EF 70-300mm f/4-5.6L IS USM. It is all well and good saying that this is best or that is the best, but I shot exclusively on a Canon 50D with a Sigma 18-250mm f/3.5-6.3, which is significantly cheaper, and lighter.
Water proof Bags:
You should come with Water proof bags for your photography Cameras as chances are high rain find you in the Jungle while on the photography excursion and this best to protect your camera from Water.
Other Gears:
Strong Hiking Shoes, trousers, long sleeved shirts, Jackets & jumpers and insect repellents should not miss on your parking list as the weather conditions tend to change.
