Fiji
To find Fiji's best beaches, look beyond the main island of Viti Levu. Many islands and most resorts have lagoons, where protective reefs calm the waves; low tide can turn lagoons into shallow wading pools. You'll find the country's best collection of silken sands on the Yasawa Islands, including several good options on Yasawa, the northerly island of the chain. The Mamanuca Islands also offer some excellent choices. For an unusual option, consider an offshore beach. As tides come and go, pristine sandbars appear. They make a great base for snorkeling, and some resorts will drop you off for a private, romantic afternoon.
