If time or stamina is a problem you can join the Kokoda Track in the middle. Airlines PNG (http://www.apng.com/) flies to Efogi, Kagi and Manari and from Port Moresby, as well as to Kokoda. The southern starting point can be reached by road from Port Moresby. Kokoda can also be reached by road from Popondetta, which receives regular flights by Air Niugini (http://www.airniugini.com.pg/).
