Thien Cung Cave - The Big Attraction of Halong Bay

Thien Cung Cave As we made our way to the big entrance of the cave I saw special lights glowing on the far inside of the cave. I felt the coolness of the sea breeze pushing me gently toward the grotto while the instructive lights invited me to come in. At this occasion I felt that my heart was beating very quickly because of eagerness and excitement to explore the cave.
