At first glance, it’s hard to believe that vibrant Norfolk Island could have a dark past. Yet during the 19th century, the now-peaceful Australian retreat was a convict colony, home to criminals who’d been banished into exile. Today, the archaeological remains of the penal colony have UNESCO World Heritage status and are revered for their historical significance. You can visit the settlement’s remains, an eerie yet beautiful collection that includes a jail, a cemetery, lumbar yard and salt house.

On Vanua Levu you can pick your pleasure; a rainforest hike, a coconut plantation tour, a relaxing soak in a Savusavu hot spring.

Jean-Michel Cousteau (son of Jacques) runs an ecologically responsible dive centre that offers courses and packages for divers of all levels of experience.

The pink sands of Champagne Beach spill into warm waters filled with wrecks and reefs begging to be explored by Espiritu Santo holiday-makers.

Divers can wave hello to “The Lady,” one of the many intact artifacts of the wreck of the SS President Coolidge.

Fiji's largest island, home to capital Suva, offers some wonderful beaches. Palm-fringed Natadola Beach, reputed to be one of the best beaches in the world, is a picture perfect crescent of powdery sand leading to dramatic cliffs. Coconuts hang overhead and the striking azure lagoon entices swimmers.

Tradition collides with pop culture in Tokyo, where you can reverently wander ancient temples before rocking out at a karaoke bar. Wake up before the sun to catch the lively fish auction at the Toyosu Market, then refresh with a walk beneath the cherry blossom trees that line the Sumida River. Spend some time in the beautiful East Gardens of the Imperial Palace, then brush up on your Japanese history at the Edo-Tokyo Museum. Don’t forget to eat as much sushi, udon noodles, and wagashi (Japanese sweets) as your belly can handle.
