Halong Bay, Vietnam
Vietnam's Halong Bay and its almost 2,000 islands were declared a UNESCO World Heritage Site in 1994 giving an official stamp of recognition to a natural wonder that has captivated painters and poets for centuries. Halong City is a convenient base before setting out for places like Cat Ba Island and smaller islets with underground caves and diverse wildlife. Some travelers come here for active days filled with kayaking, caving and islet-hopping but you can also sit back and simply admire the stunning setting. As you sail along, you may feel like you are floating through a traditional Vietnamese painting.
