Luon Cave is located on Bo Hon Island, about 14km to the south of Bai Chay Tourist Wharf and 1 km away from Surprise Cave. Luon Cave has the shape of an arc with 60 meters in length and 2.5 – 4 in height depending on the tide. Because of the limited height, the only way to visit Luon Cave is by a small boat or a kayak. Especially, when the tide rises, visitors have to stoop down to pass through the cave. Halong Bay is well-known for its impressive cave system, however, the Bay does have many caves like Luon Cave. The cave is a perfect combination of natural features including rocky cliffs, the mountain’s size and form, the color of clouds and sea waters, and the high biodiversity.
The perfect combination of lime-stone mountains and jade-green sea makes Luon Cave a unique site to visit on Halong Bay. Furthermore, Luon Cave is a preferred place of tourists for kayaking.
