The Yasawa Islands are a group of islands in north-western Fiji. Approximately 30 resorts are spread through the 12 major islands in the group. Most resorts provide basic accommodation and meals with access to natural and cultural sites.
The quickest and best way to get to the Yasawa Islands is by Seaplane. Pacific Island Air offer flights in their 10 passenger Otter seaplane and a 4 passenger Beaver plane. Both planes are new or near new (2014) and can get you there within 20 - 30 minutes. Flights depart from Nadi airport. Pacific Island Air also offer helicopter transfers.
There are a good range of Backpacker's available, often run by the islanders themselves.
Increasingly, more upmarket resorts are springing up in the Yasawas.
