Luon Grotto- Halong Bay
Situated on Bo Hon Island, 14 km south of Bai Chay Beach is the Luon Grotto. In front of the grotto is Con Rua Islet, and the Sky Gate is one the right. Here the cliffs stretch vertically out of the pure blue and smooth water. At the water- level, an arched entrance leads to the grotto, just at the base of the island. Passing through the pretty entrance, you come across a tranquil round lake, surrounded by luxuriant trees and many orchids hang their sweet- scented flowers. In the lake, many species abound: shrimp, fish, crab and cuttle- fish.
This is an enclosed group of islands. It connects with the sea via a 4- metre- wide, 100- metre- high mouth. Inside the grotto, the 1km2 brackish lake is surrounded by mountains. On the cliff one still find traces of fossils of fresh- water snails, which prove that men used to live and this must have a deep valley then.
