Viet Hai Village is located within Cat Ba National Park in Cat Hai Island District, opening out to Lan Ha Bay. The village can be accessed either from the forest or from the bay. Due to its winding paths through the forest, the village was previously rarely visited and remained almost entirely isolated from the outside world.

Recently, Viet Hai has begun to see tourism investment and is now attracting a significant number of visitors, both domestic and international. It has become an ideal spot for eco-friendly activities such as cycling tours and trekking, allowing visitors to immerse themselves in nature.

Monkey Island

Monkey Island is the second-largest island in the Cat Ba archipelago. It is situated in the middle of Lan Ha Bay and was formerly known as Cat Dua Island due to the abundance of wild pineapple trees. Currently, the island is home to over 20 monkeys. These monkeys often come down to the beach, interact with tourists, and are quite friendly. However, they can sometimes take items from visitors or, if not approached carefully, may cause injuries.

Luon Cave

Luon Cave is located among a group of secluded islands in the bay, with a single entrance to the sea that is about 4 meters wide, 3 meters high, and 100 meters long. Inside, a brackish water lake is surrounded by mountains on all sides, covering an area of nearly 1 square kilometer. The cave walls still bear fossilized freshwater snail shells. Such caves are rare in Lan Ha Bay, making it an ideal spot for kayaking. Visitors can enjoy the serene natural surroundings after passing through the entrance of Luon Cave by boat.

In 2009, Cai Beo was recognized as a national heritage site, making it one of the largest ancient fishing villages in Vietnam. It is home to over 500 households engaged in fishing and aquaculture activities in the bay. To reach Cai Beo Fishing Village, tourists typically depart from Cat Ba Island and travel approximately 20 kilometers to reach the village, where they will see the floating houses bobbing on the water, tightly clustered together like a miniature city.

Bright Cave – Dark Cave


Hang Sáng Tối (also known as Bright Cave – Dark Cave) is located on the water surface, stretching 70 meters through the mountain, approximately 12 kilometers from Ben Beo. To visit the cave, tourists typically have to paddle a small boat or kayak. Hang Sáng Tối is an unmissable destination for tourists exploring and relaxing in Lan Ha Bay, especially for those staying overnight on cruises. It is also a popular stop for day-trip boats taking visitors around Lan Ha Bay.

Sports Activities

Climbing mountains on Cat Ba Island is a popular activity that attracts both domestic and international tourists. There are dozens of climbing spots on islands in Lan Ha Bay, on the mainland, and around the Cat Ba area. Here, climbers can find challenging rock faces that cater to those who enjoy this adventurous sport.

In addition, tourists can also swim and kayak. For convenient kayaking spots, it’s recommended to either rent a boat for exploring the bay or purchase a guided kayak tour. Typically, boats will take you to calm areas near the shore to facilitate easier paddling and ensure safety. Some convenient locations include Dark Cave – Bright Cave, Luon Cave, Secret Cave, and Ba Trai Dao Beach.

5. Dining

The cuisine in the Lan Ha Bay area mainly consists of seafood, with popular choices including sea cucumbers, abalones, mullets, clams, shrimp, and various types of shellfish. Seafood can also be purchased as souvenirs, with prices ranging from approximately 500,000 to 700,000 VND per pair of sea cucumbers and 200,000 to 250,000 VND per kilogram of abalones.

Previously, Lan Ha Bay had many seafood farms where tourists could dine on-site. However, nowadays, you’ll have to dine on the mainland, on Cat Ba Island, or organize BBQ meals with seafood purchased yourself on permitted beaches such as Monkey Island or Freedom Island.

6. Tips

When dining on seafood in the Lan Ha Bay area, tourists should inquire about the prices before purchasing, especially during the peak summer months from May to August.

Only swim in permitted areas, and be sure to wear a life jacket when swimming far from shore to ensure safety.
