Otherworldly landscapes:
7 of Vietnam's best cave experiences by CNN

On July 19, 2019, CNN travel published an article about 7 of Vietnam's best cave experience.

Quang Binh province in central Vietnam is particularly famous, thanks to the UNESCO-protected Phong Nha-Ke Bang National Park -- also known as the Kingdom of Caves. Last year alone, the region welcomed more than 3.9 million visitors, representing an 18.2% uptick compared with the year prior.
"Vietnam has some of the best caves in this world. The temperatures are pleasant all year, the jungle scenery is beautiful, there are stunning formations... It's all untouched and pristine -- nothing's been damaged," Howard Limbert, technical advisor at the Quang Binh-based Oxalis adventure tour company, tells CNN Travel.
"My team [the British Cave Research Association] has explored more than 500 caves in Vietnam. But we've still only explored about 30% of this area. There are many, many more caves to be discovered."

The Article mentioned about discoveries and tourist activities at Son Doong and Hang En caves, Hang Va and Nuoc Nut Caves, Tu Lan Cave system, Paradise cave, Tam Coc cave and Sung Sot cave in Ha Long bay.
