Beautiful view from Thien Canh Son Cave

Hidden in Cong Do Nature Reserve, which encompasses about 1,600 islands and islets of various sizes, the entrance to Thien Canh Son Cave is camouflaged by the undergrowth of the forest canopy, and there is a short climb up 60-70 rock stairs through the thick foliage to reach it.

Inside the cave are three caverns, each spectacularly filled with stalactites and stalagmites forming unique structures that locals believe resemble flowers and animals, that create a dreamlike fantasy world. The ceiling is covered in glistening stalactites hanging like chandeliers and the natural light streaming into the cave combined with the multi-colored artificial lighting creates a dramatic and surreal heavenly effect by which the cave is named
