I have spent a few weeks in Fiji traveling and like a lot of travelers was completely confused when deciding what to do. This guide is for those who only have a week.
Arriving early in the morning at Nadi (if later flight stay a night at smugglers cove and miss a day on the islands): go straight to Denarau port stopping off to buy plenty of water. Then get on the Yasawa Flyer to your first island.
On a budget– spend two days in Waya Lailai Island at the Ecohaven for the summit walk at sunrise, then two nights in Matacawalevu island at White Sandy resort; finishing off at Nabua Lodge for snorkeling at the blue Lagoon-this can be booked through awesome adventures Fiji using the Bula Combo Pass
Splash the cash– spend two days at Waya LaiLai Island at the Ecohaven for the summit walk at sunrise, then a day at Nanuya Balavu Island at the Mantaray resort to see the Mantaray’s; two days at Nacula Island at Nabua Lodge to go to the blue Lagoon and finish it off at South Sea Island for the free water sports. This will seems like a strange
route, but will maximize the activities you can do.
Enjoy Fiji time.
