Three things I'd recommend if you're visiting Nadi, Fiji. 1. Stay a few nights at Tropica Island Resort and enjoy sunset happy hour. Also would recommend getting the rooms with a private plunge pool. 2. Book a day on Cloud 9 and eat wood-fired pepperoni pizza in the middle of the Pacific Ocean. The water is magnificently clear for snorkelling and they have a DJ spinning all day. 3. Go River-Tubing in Navua, Fiji. It's an early morning, long drive and a long day but it was well worth it. Even, when the rain was pelting down and we were being thrown from side to side in the rapids (I nearly lost an eye contact), it was a fun and cultural experience.
