CNBC said though international tourists to Vietnam typically head north to Hanoi and Ha Long Bay or south to Ho Chi Minh City, central Vietnam is well worth exploring.

The central region has long been famous on the country's tourism map for three UNESCO heritage sites - ancient town Hoi An, former imperial capital Hue, and My Son Sanctuary in Quang Nam Province - and popular beach city Da Nang.

Quy Nhon Town, with a 42-kilometer coastline, dubbed the "Maldives of Vietnam," is now a rising star on central Vietnam's tourism map as a quieter, less touristy destination with a mostly fishing population heading out to sea in coracles to earn a living."

Another attraction to the country’s interior is the colossal Son Doong Cave," the channel said. Son Doong in Quang Binh Province is declared the world’s largest and opened to tourists in 2013.
