If there's a more soothing, romantic way to explore a new destination than a river cruise, then we certainly haven't found it yet. Swan down the waterways of the world in a luxurious cruise-liner, punctuating port stops with lounging by the lido, hitting the gym or dance floor and enjoying freshly-cooked seafood in onboard restaurants. If you're longing to experience the power of the Yangtze, the wide waters of the "Blue Danube" or the medieval charm of the castle-fringed Rhine, a leisurely cruise will sail you through the perfect balance of scenery and sightseeing. And if the thought of all those verdant river valleys and soaring tree-clad hills isn't already tempting enough, why not throw in a themed tour element for extra allure? Whether your passion is wine-tasting, cookery or golf, there's a cruise ship out there ready to ply you with it!
