One of the biggest caves in the UNESCO Biosphere Reserve of the Cat Ba archipelago, Trung Trang has drawn thousands of visitors each year to witness its enchanted beauty of natural stalactites in various shapes. This cave is also a popular spot on many Halong Bay cruises’ itineraries. Let’s find out more details of Trung Trang Cave in this post.

Introduction & Legends

Trung Trang is a 300-meter-long natural cave that is carved out of a mountain. Inside the cavern is a masterpiece of nature, with impressive stalactites and stalagmites in unique shapes that have developed over millions of years.

Apart from its breathtaking natural beauty, Trung Trang Cave is well-known for its intriguing mythology related to the Cat Ba archipelago. It used to be a stunning archipelago and a strategic point of the country. When foreign invaders attacked the area, Lady Trung Trang called on the young men to battle the enemy in the sea and protect their land. After defeating the invaders, Lady Trung Trang went back to the cave to live and defend the island. The locals then gave the cave the name Trung Trang as a token of appreciation for Lady Trung Trang's kindness.

Geological Features

Following a long, winding path, visitors will immediately see statues of a woman nestled on a cliff and a giant python in the cave entrance, which represents the Lady Trung Trang's mascot as though to guard the peace of the cave inside.

Deep into the cave, there is a high dome filled with stalactite blocks that are still whole and gleam like crystal. When paired with the dazzling blue, red, and yellow lights, it gives us the impression that we are in a treasure trove of gold, silver, and diamonds belonging to ancient gods.
