Seven barge tunnels located along the southern edge of Karavia Bay. The present day road has been explanded, but during the war ran along this same path. Today, all the tunnels are empty. Some are used for shade for passengers waiting for buses.

Barge Tunnel (Landing Craft Protection Cave)
Four Daihatsu Landing Barges lined up nose to tail in a long passage cut into the hill by Japanese and POW labor. Presumably, they were used to ferry supplies around the coast at night, or held in readiness in case of emergency. Parallel tunnels used to house supplies and offices. These boats would have been winched down to the sea on a long track from high above sea level. There were a totoal of seven tunnels in the area, but the one has anything still inside. Locals guide visitors through the tunnels for a fee of 5 Kina.
