There is a good chance of successfully tracking the mountain gorillas but it is by no means guaranteed.
If lucky, you will spend 1 hour with the gorillas often in dense vegetation exposed to the elements. Although the guides will advise that a distance of at least 7 metres should be maintained between you and the gorillas there is nothing stopping the gorillas from getting closer on occasions. If they approach you, move back slowly.
Gorilla tracking in Bwindi Impenetrable National Park, one of the oldest forests in Africa at about 25,000 years old, is at an altitude of between 1,100 – 2,600 metres above sea level. There is an average rainfall of 1,500mm, an with its high ridges and peaks provides the ultimate home for the mountain gorillas. You should be prepared for a whole day of trekking. The hike could take as long as 9 hours through arduous and often off-trail terrain. A person contemplating taking on such an adventure must be physically fit and must be able to cope with the demands of the steep, dense, rugged, uneven and often slippery terrain.
Gorilla Safaris in Bwindi, Uganda, nowadays concentrate on two main regions, one of these is known as Buhoma and the other Nkuringo. These two locations share half of the world's remaining mountain gorillas at a population of roughly 320 gorillas living in 15 groups. Aside from gorillas, Bwindi also has healthy populations of other mammals including chimpanzees, red-tailed and blue monkeys, black and white Colobus and a small herd of elephants to name a few. Bwindi is also one of the best birding regions of Uganda with 350 different species.
