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 on 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 high dangerous stone walls.
Monkeys run to and fro in groups, benjamin fig trees
shade the landscape 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-meter-wide, 100-meter-long, and
3-meter-high mouth. Inside the grotto, the 1-km2
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 there and this must have been a deep valley
then.
The beauty of the site, is the mingling of a number
of factors: the mountain's size and form, the colour
of the water and the clouds.
