Sung Sot Cave, Luon Cave, Trong Cave, Trinh Nu Cave and Dong Tien Lake are all the well-known spots on this island.

Inside these caves, a system of stalagmites and stalactites in various shapes and sizes adorns the sparkling and mysterious appearance of the world behind the limestone walls of Bo Hon Island.

1. Sung Sot Cave

Sung Sot Cave, also known as Surprise Cave, is the largest cave on Bo Hon Island in particular and in Halong Bay in general. This cave perches on a mountain cliff, which is about 25 meters above the sea level. After climbing a 100-step stone stair, tourists will reach the narrow entrance of Sung Sot Cave, which is hidden under the luxuriant trees of the mountain.

The total area of the interior of Sung Sot Cave is about 12,000 square meters, which is divided into three separate parts. The first part of Sung Sot Cave is the smallest one, which has a small lake inside formed by the flow of rain through the stone cracks. The second part of this cave is even much larger than the first one. This is the room for the stones in the shapes of a horse and a sword, which reminds people about a famous Vietnamese legend. The third part of Sung Sot Cave includes a royal garden with a lake and various types of plants, where tourists can enjoy the fresh and tranquil atmosphere as well as contemplate the picturesque nature.

Like its name, Sung Sot Cave will for sure make all tourists surprised at first sight. This cave is like a splendid opera house of the ocean. The striking stalagmites and stalactites inside this cave, along with the colorful lights combine together to make an appealing visual effect. You may feel as if you were getting lost in a maze with thousands of mysterious things waiting for your discovery.

2. Luon Cave

While Sung Sot Cave on Bo Hon Island is a world of secret stories, Luon Cave is like a heaven gate leading to a natural wonderland. Luon Cave is a tunnel-shaped cave located at the foot of a limestone mountain. The effect of waves and water flow in the area of Bo Hon Island contributed to the formation of this unique site, which is a 100-meter length arch-shaped cave. Since the width and height of Luon Cave is not enough for a cruise ship to get through, tourists have to use a kayak or dinghy to reach the other side.

Passing the tunnel of Luon Cave, tourists will get to a 1-square-kilometer lake, which is enclosed by gray limestone cliffs of the high mountains. This lake is an airtight area with gentle wind and tranquil water surface. The lake of Luon Cave is a large and clear mirror reflecting the gleams of the mountains and trees around it. So peaceful is the atmosphere there that you can even hear the sounds of the oars touching water, the songs of some hidden birds and the sounds of the winds blowing through the trees. Luon Cave is a place where you can get off your chest all the pressure and exhaustion so as to feel your soul in nature.

3. Trong and Trinh Nu Caves

Every cave in Halong Bay has its own story, and Trong Cave and Trinh Nu Cave are not the exception. These two caves are associated with a love story with a sad ending of a couple from a fishing village. Due to the poverty, the boy had to put to sea in order to get enough money to marry his lover. At the same time, the girl was forced to marry a cruel landlord, but she did not agree, then she was exiled to an isolated island. Starving and exhausted, the girl turned into a stone on a stormy night. When the boy knew all those things, he came to find her hopelessly. Finally, he also turned into a stone statue.

The caves where the couple turned into the stones are Trinh Nu Cave and Trong Cave that you can see nowadays. In Trinh Nu Cave, besides the majestic stalactites, tourists will catch the sight of a stone in the shape of a long-hair girl looking toward the sea. Opposite Trinh Nu Cave is Trong Cave, where tourists can see a stone statue of the boy and listen to the splashing waves from the sea, which is like the drum beating. Trong Cave and Trinh Nu Cave are not only attractive thanks to the natural beauty of these caves but also famous for a touching love story.

4. Dong Tien Lake and Cave

Dong Tien Lake and Cave is the combination of a limestone cave and a sea water lake, both of which are named Dong Tien. Sometimes, this spot is also called Dong Tien Lake. The name of this destination came from a story that due to the picturesque and peaceful scenery, this lake used to be visited by the fairies from Heaven each afternoon. Some other people suppose that this cave is as appealing as a fairy land, so it was named Dong Tien. Of all the destinations on Bo Hon Island, Dong Tien Lake and Cave is the only one that has not developed tourism.

Dong Tien Lake and Cave nowadays can retain all the unspoilt and pristine beauty of a cave without the impacts of humans. Except for the research and preservation activities of the scientists, tourism activities there are not allowed. Therefore, only some groups with specific purposes are able to reach Dong Tien Lake and Cave. Dong Tien Cave has three parts, and the third part leads to the entrance of Dong Tien Lake. Although Dong Tien Lake is not large, the system of flora and fauna around this lake has a high value in terms of science, which provides a favorable condition for the scientists to do research.
