Thien Long cave – Cat Ba Island, Cat Ba Traveller Reviews
Thien Long is located in Phu Long town, which is isolated from the area around.
Going around the cave, you will see the root of hundred year Si tree which was planted on the top of the mountain (Si is a plant symbolized something old and holy, and usually grown in temples, pagodas, and communal houses in villages). The cave’s air is so cool and fresh; at times some bats flew over our heads and made us nervous.
You could go around the cave and enjoy the extraordinary figures of stones; freely to imagine and guess what form stones are. That is very interesting!
