Mt Giluwe is a striking mountain when seen from the Highlands (Okuk) Hwy between Mt Hagen and Mendi. It attracts climbers from around the world who are committed to summitting the highest volcanic peaks on all seven continents – the Volcanic Seven Summits. As part of the Indo-Australian continental plate, PNG has been contiguous with Australia in past ice ages, and is considered part of the Australian continent. And at 4367m, this old shield volcano holds the title. From the trailhead near the highway it takes about six hours to reach the cave generally used as base camp (bring your own tent and supplies). From the cave, it is about three hours up to the peak. Paiya Tours, based in Mt Hagen are recommended organisers of this trek.
Mt Giluwe Lodge sits on the highway between Mt Hagen and Mendi (PMV K10 either direction). It has clean and comfortable rooms and a restaurant (breakfast/lunch/dinner K25/20/30). The lodge can organise the all-essential local mountain guides (K150). Don't underestimate the cold temperatures, altitude and exposure of this trek. Many trekkers first tackle Mt Hagen in an effort to acclimatise for the altitude.
