Vanuatu is a "Y" shaped chain of 83 islands lying 2,500km northeast of Sydney Australia. The main accommodation is located on the island of Efate, the two other popular island destinations are Tanna Island which is famous for its volcano and Espiritu Santo for its diving.
There are several active volcanoes above and below sea level. The last major erruption occured in 1945. Because of its volcanic nature many of the islands in Vanuatu are steep with the highest point being Mount Tabwemasana standing at just under 1900m from the island of Espiritu Santo.
