There are about 20 villages along the 220 km trail that runs from Gabagaba in Central Province, across the rugged Owen Stanley Range to the north side of the Peninsula in Northern Province.
The villages include Arapara, Jaure, Natunga, Kovio, Laruni, Nepeana, Barumbila and Bofu.
Experienced trekker Peter Gamgee said the trail, used during World War 2, now provides opportunities for the locals after it was recently rediscovered.
Gamgee had mapped out the trail in 2011 when he was one of the first to complete the track alongside his son.
