Between the majestic mountains, covered by lush-green trees and bushes, in Cat Ba Island, Vietnam, is Hoa Cuong Cave, one of Vietnam's most popular yet untouched beauties. Also named Diamond cave, it's known for its unique shimmering beauty, which casts a magical spell on visitors. Multiple stalactites and stalagmites glitter, giving a diamond-like appearance. This is not the only exceptional feature of this gigantic cave; from inside, it's no less than a fairytale with these formations taking shapes of humans and animals. Also, there is a pristine lake which further adds to its beauty.
