I. Location of Luon Cave
Luon Cave is a part of Bo Hon Island, which is about 14 kilometers from the mainland of Bai Chay City. Known as the island of amazing things, Bo Hon Island is an outstanding location in Halong Bay that most tourists choose as a next stop on their journey discovering the bay.
The surrounding area of Luon Cave comprises many well-known places of interest in Halong Bay. In front of Luon Cave is Con Rua Island (Turtle Island), and on the right of this cave is the Heaven Gate. Not only that, in the area of Bo Hon Island is Sung Sot Cave, which is the most magnificent cave in Halong Bay. Tien Cave and Trinh Nu Cave are also famous caves located near Luon Cave.
II. History of Luon Cave
Although Luon Cave is not as large as other caves in Halong Bay, it has been formed over millions of years thanks to the impact of sea wind and water. The effects of the tide, along with the water flow, gradually eroded the foot of the limestone mountain and created a natural tunnel. This is the Luon Cave that we can see today.
Up to now, visitors can still observe the remains of the ocean on the mountain cliffs of Luon Cave. Fossil shells of oysters, snails, and crabs serve as evidence of life that existed there millions of years ago. The sea level used to be higher than it is now, and before emerging above the sea surface, Luon Cave was once an underwater cave.
III. Highlights of Luon Cave
Many tourists consider Luon Cave as a gateway opening to a hidden wonderland of water and limestone mountains. Passing through Luon Cave, visitors often leave their stress behind and feel a deep connection with nature.
Luon Cave is a tunnel about 100 meters long, 4 meters wide, and 3 meters high. Although it is not very large compared to other caves in Halong Bay, it is still unique and mysterious. Located at the foot of a towering mountain, the cave can only be accessed by passing underneath it by boat, which is why it is called “Luon Cave.”
The cave features an arch-shaped entrance leading to a tranquil lake of about 1 square kilometer. Surrounded by high mountains, the lake is protected from waves and strong winds, making its surface calm and peaceful. It looks like a precious jade hidden within the mountains of Bo Hon Island.
On all sides of the lake are limestone cliffs covered with green bushes, colorful orchids, and ancient trees. The still water reflects the surrounding scenery like a mirror, creating a perfect natural picture that fascinates visitors.
IV. How to Get to Luon Cave
Luon Cave is located on one of the most popular islands in Halong Bay, so it is quite easy to reach. From Bai Chay Wharf or Cai Lan Wharf, you can join a cruise whose itinerary includes Luon Cave or hire a private boat. Many tourists choose Catherine Cruises for their journey, as it provides convenient access and high-quality services while exploring famous attractions like Luon Cave.
Due to the limited height of the cave, only small boats can enter. Cruise ships will stop outside the cave, and visitors can then rent a kayak or take a small boat rowed by locals to explore further. The cost of renting a kayak starts from around 50,000 VND per person.
The best time to visit Luon Cave is from February to June and from September to October, when the weather in Halong Bay is pleasant and suitable for outdoor activities.
