2. Formation History and Meaning of the Name
Trung Trang Cave was formed millions of years ago through the natural weathering and erosion process from rainwater seeping into the limestone blocks. Initially, the cave was called "Bat Cave" by the locals due to the large number of bats living inside. During the anti-American war, it was a strategic military base and known as "Naval Cave".
The name "Trung Trang Cave" today is associated with the folk legend of Lady Trung Trang – a goddess revered by the people of Cat Ba as the patron saint of the island. According to legend, the Lady once appeared to help the villagers overcome many invasions, maintaining peace and prosperity for the inhabitants. Therefore, naming the cave after her is a way for the people to remember and express their deep gratitude to this sacred deity.

Stepping inside, you will be captivated by the diverse shapes of limestone formations, exquisitely "sculpted" by nature. Thanks to the well-placed lighting, the details inside the cave appear clearly, sparkling and magical like a vivid painting in the heart of the limestone mountains.
The most striking feature of the cave is the uniquely shaped stalactites and stalagmites.

The flapping of wings and calls of the bat colony echo through the space, contributing to the mysterious and attractive atmosphere for visitors to explore.
Besides, the cave is also home to many insects and reptiles that have adapted well to the dark and humid conditions inside. The water droplets falling from the cave ceiling form small puddles, providing an ideal habitat for endemic and rare species. To protect this valuable ecological balance, the management of Trung Trang Cave applies strict measures such as controlling the lighting in the cave, and also requires visitors to maintain order, avoid making noise, and not litter.
The air in the cave always maintains freshness and coolness thanks to the natural air exchange through the crevices and vents. This not only helps preserve the ancient stalactite structures but also maintains the sustainable development of the unique ecosystem, contributing to the distinct value of Trung Trang Cave in the Cat Ba National Park complex.
