Huon Gulf is in Papua New Guinea.
Huon Gulf is the area on the northern coast of Papua New Guinea occupied by Morobe Province, which has a population of close to 600,000. The province, which is drained by the Markham River, has 171 languages. Tok Pisin (pidgin) is the lingua franca. The province gets much of its income from the importance of Lae as a port that exports produce from the Highlands, but the Markham Valley in the province is also an important agricultural area. Oil exploration and mining are growing in importance and there is a timber industry in the Bulolo area.
Huon Gulf offers spectacular scenery, accessible diving spots, and a range of climates from sub-alpine and alpine to tropical. The Province's jungles and forests offer over one thousand species of birds and mammals, including the Raggiana Bird of Paradise, the Cassowary, a flightless emu-like bird, and the tree-kangaroo. Over 15,000 species of plant have been identified and there may be many more.
The Province has many battlefield relics from World War II, with submerged shipwrecks, aircraft and artillery. It receives many visitors from Japan.
Lae can be reached from the PNG Highlands by the Highlands Highway. There are no coastal roads but Lae can also be reached from Madang by taking the Ramu Highway that follows the Ramu River and connects with the Highlands Highway to follow the Markham River down to Lae.
Apart from the Highlands Highway, road connections are limited in Morobe, with the exception of a road that branches off the Highlands Highway to the left to go up to Wau and Bulolo. The road is good from Lae to Nadzab airport. Public Motor Vehicles ply the Highlands Highway and the Wau-Bulolo road and are a relatively inexpensive, although not particularly safe, form of transport.
The scars of the war remain and live mortars, munitions, plane wrecks, and huge bomb craters can be seen. The trek should take four to five days. It is tough 8-9 hours walk each day, with hospitality in villages that have little other contact with the outside world. There is an abundance of wildlife and magnificent flora and fauna. The trail is almost always followed from Wau to Salamaua, allowing you to reach Salamaua on the last day with a recuperative rafting trip down the Francisco River to Salamaua.
