Old world charm resurfaced on the calm water of Halong Bay, Vietnam with the launch of a magnificent five star vessel Emeraude modeled in the tradition of the grand old single wheeled paddle steamer of the colonial era. One of the great natural wonders of the world and a UNESCO World Heritage Site, Halong Bay covers an area of 1,500 km² over which are scattered thousands of limestone islands and grottoes rising from the clear, emerald waters of the Gulf of Tonkin.
