However, we highly recommend you take a Cat Ba Island cruise which includes kayaking in its itinerary.

4. Conquer Ngu Lam Peak

Hiking up the Ngu Lam Peak is a must-do for any hikers. Ngu Lam is an incredible hiking spot to soak up the wilderness of Cat Ba National Park. To conquer the peak, requires a lot of effort and sweat but still worth a mesmerizing view of the top hills over the scenic island. It takes around 45 minutes up and 30 minutes down to conquer the route to Ngu Lam Peak. The majority of the uphill path is in good condition, but you should be careful of the rough trail with steep drop-offs in the middle of the jungle.

There are two viewpoints that you should catch the sights of both. The first one is a multi-tiered watchtower offering the surrounding views. The second one is far more spacious without any barriers. Here you can feast your eye on a 360-degree panoramic view and let your hair down after the draining hike.

6. Pay a visit to Hospital Cave

Cat Ba Island has plenty of small and large caves to discover. Most of them are renowned for primitive beauty and multi-shaped stalactites and stalagmites. One of the most worth visiting is the Hospital Cave, a huge complex that used to be a hospital to treat the wounded for over 10 years during the Vietnam War.

The massive space at Hospital Cave

Built as a three-story complexity, Hospital Cave boasts a cinema, a swimming pool, and plenty of creepy mannequins dressed in Vietnamese soldiers. It is quite horrifying to wander around the mostly empty rooms and witness the represented scenes under the dim lights. However, you definitely need a local guide who shows you the resilient history of the Vietnamese. To enter the cave, you have to pay an entrance price to Cat Ba National Park of 2 USD.

7. Learn history at Cannon Fort

Set location on the top of the 177-meter High Point, Cannon Fort is known as a sunset viewpoint rather than a historical site. Nevertheless, most tourists haven’t heard about the history of this fortification dating back to the 20th-century struggles between Vietnam and the West. Considered an excellent strategic lookout point for marine and air attacks, the island was invaded by the Japanese during World War II. They built an underground system of tunnels and trenches connecting the cannons and many other infrastructures. Since then, Cannon Fort was used as a defense post by the Vietnamese during the French and American Wars.

At Cannon Fort, you can find a resemblance to Cu Chi Tunnels in Ho Chi Minh City. Here you can learn about the historical Vietnamese victory and wonder how this little country could shoot down American planes over the Gulf of Tokin.
