It used to be that backpacking trips to Fiji involved a bus ride from Nadi to Suva, then a ferry to somewhere like Ovalau, Savusavu, Taveuni or Kadavu. No more. These days young budget travelers are lining up to go to the Yasawa Islands, a chain of 16 large volcanic islands and dozens of smaller ones roughly 35 km off the west coast of Viti Levu.
