East Tanna is the 'active' part of the island, in more ways than one. Mt Yasur dominates the landscape, its ash-laden smoke smothering the vegetation and creating a surreal monochrome scene on the western ash plain. There was once a large lake here, but following heavy rains in 2000 it burst its banks and drained out to sea through Sulphur Bay.
Along the coast to the north and east of Yasur are a string of black-sand and white-sand beaches, best explored from the headland of Port Resolution. Several kastom villages put on traditional dances for visitors and there are opportunities for jungle hikes and bathing in hot springs. If you're happy to stay in basic island bungalow accommodation, spending the night near Yasur (and climbing at sunrise) is an experience not to be missed.
