Sung Sot (Surprise) Cave

Sung Sot Cave, or Surprise Cave, ranks among the most popular caves in Halong Bay. Situated on Bo Hon Island, it was first discovered by the French in 1901. It takes a little trek to reach the cave’s entrance but once you are in, you will be amazed by the natural structure of this cave and various stalactites and stalagmites.

To access the cave, visitors must climb approximately 100-150 stone steps leading from the dock to the cave entrance. While the steps are generally manageable, they can be steep in sections, so it’s recommended to wear sturdy shoes.

Inside the Cave, Sung Sot Cave has two main chambers, with wide pathways and some gentle inclines to navigate within the cave. The total walking and exploring distance inside the cave is around 500 meters.

Sung Sot Cave is well-lit to highlight its unique rock formations, making it ideal for photography. The largest chamber, nicknamed the “Royal Garden,” features intricate formations and open spaces for taking photos. At the cave exit, visitors can capture breathtaking views of Halong Bay. After exiting the cave, a short climb leads to a viewing platform overlooking Halong Bay, providing a panoramic vista of the bay’s limestone karsts and emerald waters.

Tien Ong Cave

Tien Ong Cave is about 20 km away from the center of Halong; it is situated in a very large area. The mouth of the cave, 50m wide and 10m high, leads to a massive underground dome of some 1,000 square meters. Compared to Sung Sot Cave, it is much less crowded and has its own distinctive charm.

The path includes a manageable set of approximately 50-60 stone steps leading up to the cave entrance, making it accessible to most travelers. However, the ground inside the cave can be uneven and slightly rocky, so good walking shoes are recommended.

Thien Cung (Heaven) Cave

Thien Cung Cave, or Heavenly Palace Cave, is situated on Dau Go Island and can be reached by boat. The cave features three main chambers, each one more breathtaking than the one before. It requires a bit of a trek but rewards visitors with a surreal experience of color, intricate formations, and ancient tales depicted on its walls.

The path to Thien Cung Cave is moderately challenging, with about 90-100 stone steps leading up to the entrance. This climb involves a cliffside trail surrounded by dense forest, so visitors should prepare for a bit of uphill walking.

Dau Go (Wooden Stakes) Cave

Dau Go Cave, often called the Cave of Wonders, is rich in history and natural beauty. It gets its name from the famous 1288 battle in which Vietnamese forces, led by the legendary military strategist Tran Hung Dao, defeated the Mongol fleet by planting ironwood stakes in the Bach Dang River. The cave, situated on Dau Go Island and covering approximately 5,000 square meters, is just 300 meters from Thien Cung Cave, making it convenient to visit both on the same trip.

Luon (Tunnel) Cave

For those who’d love to try kayaking in Halong Bay, Luon Cave is the one to go. Unlike most caves accessible by larger boats or cruise ships, Luon Cave’s low-lying entrance requires visitors to travel by bamboo boat or kayak, making the journey itself unique and intimate. This natural, arc-shaped cave captivates visitors with its impressive stone pillars, lush plant life, and serene, enclosed lagoon just beyond its entrance.

Visiting Luon Cave requires a level of comfort with small watercraft, especially kayaking. However, the cave’s limited height means that you may need to duck or stoop when passing through, particularly at high tide. This adds a small physical challenge but enhances the immersive experience.
