Nadi is the most practical base in Fiji, especially if your trip includes a late arrival, an early flight, or a ferry from Port Denarau. It has the widest spread of airport hotels, affordable stays, and easy transfer options.
The area is also useful for travellers who want to see more than one part of Fiji. You can visit gardens, markets, mud pools, beaches, and island day trips without committing to a remote resort for the whole holiday.
Stay near the airport for convenience, around Wailoaloa for casual beach hotels, or closer to Denarau if you want resort facilities and marina access.
