8 Volcano climbing
It’s possible to scramble to the top of Mount Tavurvur, near Rabaul, and to peer into the smoking crater. After crossing the barren moonscape surrounding the mountain, the steep slopes provide a challenge. There’s no track, just loose rock, and fissures letting out hot steam. You should make it to the top in about 30–45 minutes from the base. Go with a guide, take plenty of water, and set off early to beat the heat. Most hotels in the region will arrange guides.
