The central circuit starts at the Rwenzori Mountaineering Services offices at Nyakalengija. You need to arrive in the morning to allow ample time to rent equipment and meet your guides and porters. The trail begins by passing through farmland to the park boundary beyond which it follows a thick forest along the Mubuku River, crossing its Mahoma River tributary before starting a long, steep climb up onto a massive ridge to reach Nyabitaba hut. During this part of the trip you may hear chimpanzee and see black and white colobus, blue monkey and the brilliantly coloured Rwenzori turaco.
