CNBC said that many international tourists to Vietnam head north to Hanoi and Ha Long Bay or south to Ho Chi Minh City. Those who do venture to the centre typically go to the old town of Hoi An, the glitzy hotels outside of Da Nang or to the historic sites of Hue and My Son.

Unknown destinations in central Vietnam have the potential of attracting many tourists. As suggested by CNBC, two trends that will attract international visitors in central Vietnam are quiet isolated resorts in Quy Nhon and Mui Ne, and the world’s largest cave system - Son Doong Cave in Quang Binh.

First explored in 2009, only 1,000 travelers are permitted to explore it every year, a limit put in place to protect the cave, which is believed to be one of the largest and most magnificent in the world.

Other safe destinations which make the list are Normandy in France, the ‘other’ islands of Greece, Kagawa in Japan, Dandenong in Australia, New Mexico, and Saba and Saint Eustatius./.
