The Emeraude cruise line has been offering cruises on Halong Bay since 1910. The company began with a paddle steamer called the Emeraude owned by the Roque family who built several ships in the 1850s and 1860s to ferry passengers and goods around French Indochina. Today the Emeraude offers cruises aboard a replica steamer with 38 meticulously designed cabins that evoke colonial-era Indochina. The cruise travels among the over 1,500 limestone islands and grottoes of Halong Bay, a UNESCO World Heritage site, allowing passengers to appreciate the natural beauty from the water.
