Take the morning flight from Port Vila to Tanna. Cross the incredible ash plain by 4WD truck and find your tree-house haven beneath rumbling Mt Yasur. Climb the active volcano before dusk then witness the fireworks. Back at Port Vila, explore the cascades then head to northern Efate to Pele or Nguna for some rustic island time. Return to Vila and visit one of its three islands for lunch, dinner and snorkelling. Fly north to Santo to explore Million Dollar Point and relax at Oyster Island, taking a day trip to stunning Champagne Beach.
