Yokohama is easily accessible from Tokyo, but there’s enough to see and do here that it’s worth more than a day trip. Visit Minato Marai 21, a popular, modern neighborhood with great shopping and tons of restaurant options. TripAdvisor travelers also recommend stopping at Big Wharf (Osanbashi Pier), a uniquely shaped pier with spectacular views.

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.

The world's largest coral reef system, the Great Barrier Reef stretches almost 1500 miles into the Pacific from the tip of Queensland. Designated a Marine Park by the Australian government and a World Heritage Area by UNESCO, the reef is home to an extraordinary abundance of species and habitats. Snorkelling, diving and fishing are popular along the reef, nowhere more so than on the Whitsunday Islands, where the silica sands and aqua waters of the Coral Sea create the perfect beach escape.
