Hospital Cave is a miniature hospital built in the heart of a mountain during the war. The cave has three floors and 17 separate rooms with various functions.

The cave is a natural cave with many stalactites. The cool cave has a unique sound, with tiny drops of water flowing down from the stalactites on the ceiling.

To reach the cave, you need to climb up hundreds of stone steps and a forest trail to the top of Ngu Lam Peak.

From the top of Ngu Lam Peak, you can see the majestic beauty of the primeval forest on the islands.

The hike down from the peak takes about 2 hours. Along the way, you can see various flora and fauna specimens.

Finally, you can visit the flora and fauna specimen gallery in Cat Ba National Park. The gallery showcases a wide range of plant and animal species found in the park.
