All three places are among the greenest tourist destinations in Viet Nam and are much loved by both local and foreign visitors.
Ha Long is a natural marvel with more than 1,500 islands and inlets popping up from emerald waters that are perfect for a boat cruise.
The bay has become famous since UNESCO named it a natural heritage site and has made many travelers bucket lists.
Earlier this month, U.S. news site Business Insider also named a cruise trip through Ha Long Bay among the must-do travel experiences in Asia.
800km to the south of Ha Long is Hue, the seat of the Nguyen Dynasty from 1802 until the end of feudal Viet Nam in 1945.
The city known for its Imperial City and photogenic royal tombs on the outskirts, as well as its poetic beach, river, mountain sites and a wide range of special rice cakes.
Hoi An is just a three-hour ride to the south of Hue. Once a popular trade port in the region, Hoi An now draws tourists to its picturesque wooden houses, pagodas, street-side eateries and hundreds of tailor shops.
A travel forum run by US magazine USA Today described Hoi An as one of the 10 most beautiful places in Southeast Asia, a place where one can find “tranquility and timelessness”.
“Best Day on Earth”, a new book by the UK travel publisher Rough Guide, listed Hoi An’s full-moon festival among the world’s most extraordinary travel experiences for the hundreds of lanterns that glow along alleys and river banks around town.
The New York Times list also includes Amsterdam, Berlin, Budapest, Cuba, Montreal, New Orleans, Oaxaca in Mexico, Patagonia in Argentina and Prague.
