Vietnam’s Phong Nha-Ke Bang National Park and Ha Long bay have been named among the New York-based Business Insider’s top 20 gorgeous natural wonders around the world.

“Phong Nha-Ke Bang National Park, located in the middle of the Annamite Mountain Range in the Quang Binh province, is home to the oldest karst (or landscapes formed from soluble rocks and characterized by caves and sinkholes) formations in Asia,” said the newspaper.

Dating back over 400 million years, the bay contains over 104 km (64 miles) of caves and underground rivers.

“Ha Long bay, in the Gulf of Tonkin off the coast of northern Vietnam, is made up of about 1,600 islands and islets of limestone pillars,” said the newspaper.

According to UNESCO, a majority of the islands are uninhabited by people due to their extremely steep nature./.
