The longest, and most arduous trail in Udzungwa is the Lumemo trail, starting along the same path as the Mwanihana trail, except instead of hiking up the peak after camping at Njia Panda, the path continues for another 4 nights exiting the forest along the Lumemo river leading to Ifakara, where you'll be picked up and brought back to Hondo Hondo for a nice shower and a few much needed cold beers! This trail leads deep into the heart of the Udzungwas, to areas where few people have ever been and the wildlife there has had virtually no contact with humans.
