Here you can still glimpse the truly exotic — gilded shrines and floating markets, sampans in mist-shrouded harbours, harvested rice left to dry in the sun. But equally fascinating is the contrast of the new and the old: from skyscrapers towering over stone-carved temples to bullet trains speeding past rice paddies and tea plantations Silversea's Asia voyages offer a taste of the best.
