Sung Sot cave (or Surprising cave), one of the largest caves in Ha Long Bay, has been voted as one of 10 most beautiful caves of the world by the Association of Tourism Offices and Brokers of the Czech Republic.

Discovered in 1901 by the French, Sung Sot cave is divided into two chambers and covers a total area of over 10,000 sq.m. It is also described as an “opera house” with the beauty of thousands of magic stalactites and stalagmites. A lot of tourists are attracted by the beauty of this cave. And this is actually a good sign for the Vietnam travel company.

Other caves in the top 10 are world-famous caves such as Skocjan in Slovenia, Patagons ice cave in Argentina, Lehaman Nevada in the United States and Waitomo glow worm cave in New Zealand.
