Located in the Cat Ba archipelago, Cat Hai special zone, Hai Phong city, Cat Ba mangrove forest is mainly concentrated in the Phu Long area with an area of nearly 700 hectares. This is considered one of the largest and most unique mangrove forest ecosystems in the Gulf of Tonkin.

To get to the Cat Ba mangrove forest, visitors usually depart from Hanoi, traveling a distance of over 100km to Hai Phong. You can travel by private car, passenger car or train to Hai Phong, then continue your journey by ferry, speedboat or cable car. In particular, the Cat Hai - Phu Long cable car line of Sun World is the means of transport chosen by most tourists because of its modernity and convenience, only about 10 minutes across the sea, offering a panoramic view of the beautiful bay - very ideal for families with young children.

If you bring a motorbike or private car, you can take the ferry from Dong Bai wharf to Cat Ba, which takes 20-30 minutes, saving time and convenience. For guests from the central or southern provinces, flying to Cat Bi Airport (Hai Phong) or Noi Bai Airport (Hanoi) and then buying a combined bus + speedboat ticket to Cat Ba is also considered a quite optimal option.

From the center of the island, traveling to Phu Long commune is quite easy and has many options. Tourists can take a bus for only about VND 20,000/trip, call a taxi ranging from VND 150,000 - 200,000/trip, or be more proactive by renting a motorbike for VND 120,000 - 200,000/day. On the journey, the coastal road will captivate you: on one side are towering limestone mountains, on the other is the characteristic turquoise water of Cat Ba, creating a beautiful natural picture.

2. Unique ecological characteristics of Cat Ba mangrove forest

Cat Ba mangrove forest stands out with its diverse ecosystem and the unique adaptation mechanisms of many mangrove species. This combination has created a special ecological value, attracting researchers and nature-loving tourists to explore.

2.1 Top 7 diverse ecosystems in the area

Cat Ba archipelago is recognized by UNESCO as a World Biosphere Reserve thanks to its 7 characteristic and precious ecosystems, in which mangrove forests play a key role. These mangrove forests thrive in estuaries and tidal areas, like a strong "green shield", protecting the coast from the impact of wind and waves and erosion.

Surrounding this area are primeval forests growing on limestone mountains, creating an interesting transition between brackish and freshwater environments. Close to the coast, the tropical marine ecosystem with diverse coral reefs adds to the richness of the landscape. Inside the limestone massif is a system of dry caves and submerged caves containing fresh water full of mystery. On the high mountain peaks, Kim Giao forest combined with freshwater lakes such as Ao Ech makes the ecological picture even more vivid.

The interweaving of these 7 ecosystems not only maintains an incredible level of biodiversity but also makes Cat Ba an attractive destination for researchers and tourists. The ecological value and importance in conservation have helped Cat Ba to be assessed by UNESCO as one of the world's leading biodiversity conservation areas.

2.2 Characteristic flora with mangrove and mắm trees

When setting foot in the Cat Ba mangrove forest, visitors are easily captivated by the meandering prop roots of the mangrove trees, rising high above the water surface like natural pillars. This tree species is considered the symbol of the mangrove forest, with its special adaptability in brackish water environments: the roots can filter salt, while the leaves secrete salt to maintain life. Mature mangrove trees can grow up to 15-20m tall, creating a lush green canopy covering a large area of coastal waters.

Besides mangrove, mắm tree is also a dominant plant species in Cat Ba. This tree species is notable for its oval leaves, the upper surface is glossy green while the underside is covered with a layer of silver fluff. The most characteristic feature of the mắm tree is the system of pneumatophores rising above the ground, helping the tree exchange gases in an environment that often lacks oxygen. In addition, species such as sú and vẹt trees are also present, contributing to the increase in plant diversity in the area.

According to records, Cat Ba mangrove forest currently has 11 mangrove plant species, 11 species of salt-tolerant origin, and 9 inland species that have moved out. Each species possesses a unique biological mechanism to adapt to living conditions, forming a rich, sustainable and particularly valuable ecological vegetation.

3. Rich fauna in the mangrove forest

Cat Ba Mangrove Forest is home to hundreds of rare animal species, from migratory birds to unique marine life. The ecosystem here is not only diverse but also plays an important role in maintaining natural balance and preserving the gene pool.

Early morning in the Cat Ba mangrove forest is a great time to explore the vibrant life of aquatic birds. From the lush green mangrove canopy, flocks of white egrets call out, preparing to fly to shallow waters to feed.

Hidden among the mangrove roots are herons with brown feathers speckled with white, patiently hunting small fish and shrimp. In winter, migratory ducks appear in large flocks, covering the water's surface, creating a vibrant natural scene. When the tide recedes, the sea curlew with its characteristic long curved beak appears, digging in the mud to find worms and mollusks.

Not only a habitat, the Cat Ba mangrove forest is also an important stopover point on the East Asia-Australia migratory route. Many rare bird species have been recorded here, including those listed in the Vietnam Red Book such as the rufous-necked hornbill or the large hawk, often appearing during the two migration seasons of March-April and September-October each year.

3.2 Diverse marine life from shrimp and crabs to fish

When the tide recedes, the Cat Ba mangrove forest gradually reveals a rich world of marine life hidden beneath the alluvial mud. Under the mangrove forest is a world of hundreds of animal species - from fish, crabs, clams, to aquatic birds and endemic crabs.

In particular, the image of the mudskipper with its characteristic round eyes has become a familiar symbol of the mangrove area. This fish not only swims underwater but can also climb tree roots to hunt insects, thanks to its ability to live in both environments. In deeper waters, many economically valuable fish species such as grouper, mullet, and snakehead fish also frequently appear.

According to research, Cat Ba mangrove forest is the natural breeding and spawning ground for nearly 200 species of marine fish. In addition, the ecosystem has recorded the presence of oysters, clams, and scallops attached to the roots of trees, providing a rich food source for many other animals. Crustaceans such as small lobsters or green crabs choose submerged rocky crevices as shelter, only coming out to forage when night falls.

4.2 Exploring the mysterious Phu Long cave

Phu Long Cave is adjacent to the Cat Ba mangrove forest, hidden within a limestone mountain. To reach the cave entrance, visitors will walk along a 200m trail through the natural forest. The cave entrance is nearly 3m wide, leading to a spacious interior. Here, a system of stalactites with many unique shapes has formed over millions of years, creating a magical and mysterious beauty.

A highlight of Phu Long Cat Ba Cave is the harmonious combination of dry cave and underground lake. The front part of the cave is dry, where stalactites shine under the lights, while a clear freshwater lake appears deeper inside, with a depth of 2-3m. The temperature in the cave remains cool year-round, providing a pleasant feeling.

Typically, Phu Long Cave tours are combined with exploring the Cat Ba mangrove forest, offering diverse experiences from the saltwater ecosystem to the freshwater cave environment. Visitors should prepare flashlights or headlamps to fully appreciate the beauty of the stalactites inside the cave. The average tour time is about 45 minutes.

4.3 Clam digging and fishing experience with fishermen

Clam digging in the Cat Ba mangrove forest is an experiential activity linked to the rhythm of the tides, usually taking place during low tide, around 6am-8am or 5pm-7pm. Before starting, visitors will be provided with rubber boots, baskets, and instructions on how to identify clams and shells hidden under the alluvial mud by local fishermen. The clam digging technique requires finesse using both hands and feet to feel the hard objects under the mud, providing a fun and challenging experience.

In addition to clam digging, visitors can also participate in fishing experiences with fishermen, from removing nets, harvesting shrimp and crabs with cast nets to casting fishing rods in deeper water areas in the forest.

At the end of the journey, visitors will enjoy a fisherman's meal with freshly caught seafood such as steamed clams, boiled crabs, or grilled shells. The dishes, although simply prepared, are full of rich seafood flavors, creating an unforgettable experience.
