Located in the northern mountainous province of Yen Bai, Mu Cang Chai district is famous for its terraced rice fields which change color depending on the time of the year, from green in late spring and summer to golden yellow in October during the harvest season.

"These rice paddies in Vietnam’s isolated northern reaches have gained Instagram fame for their impressive angles in a topographically challenging region," Condé Nast Traveler said.

Meanwhile, the UNESCO World Heritage Site Ha Long Bay in Quang Ninh Province is well known for its "blue-green water, and spectacular limestone karst landforms." 

Condé Nast Traveler advised tourists to rent a junk to cruise through thousands of small vegetation-covered islands and towering limestone cliffs that dot the mist-shrouded bay.
