2. What to see and experience at Cat Ba National Park?
2.1. Ecosystem diversity
Exploring the extraordinary ecosystem diversity of the national park is an experience not to be missed. The park encompasses seven distinct ecosystems, including mangrove forests, limestone mountain forests, freshwater swamp forests, tidal flats, valleys, and more. The surrounding sea features vibrant coral reefs that serve as habitats for numerous marine species. Beyond its core area, the park also includes a scenic buffer zone of protected forests, which plays a vital role in both conservation and ecotourism.
According to recent studies, the national park is home to more than 4,000 species of flora and fauna. These include 282 forest-dwelling animals, 538 marine bottom species, 196 sea fish species, 771 terrestrial plants, 23 mangrove plants, 75 seaweed species, and 177 corals. Many are endemic to the archipelago, most notably the critically endangered Cat Ba langur, found only here. The park also shelters 153 rare species listed in Vietnam’s and the world’s Red Books, such as black squirrels and rosewood trees.
2.2. Stunning caves
Cat Ba National Park, Vietnam captivates visitors with its extraordinary cave system. Among them, Trung Trang Cave and Hospital Cave are two must-see wonders.
Trung Trang Cave lies about one kilometer south of the park’s center. Formed tens of millions of years ago, this 300-meter-long cave runs through the limestone mountain, filled with thousands of stalactites in fascinating shapes - graceful maidens, soaring eagles, and glittering crystal vaults. Each formation carries its own legend, adding mystery to the underground journey. Near the entrance stands a shrine dedicated to Lady Trung Trang, who is said to have defended the island from enemy forces.
Hidden on a limestone hillside, Hospital Cave is an impressive relic. Between 1963 and 1965, locals converted the cave into a secret military hospital to treat soldiers and shelter civilians. Reinforced with concrete, it features solid iron doors and 17 rooms arranged across three levels, including operation rooms, recovery areas, kitchens, and even a small cinema. Almost untouched today, the cave remains a powerful reminder of the resilience of the Vietnamese people during wartime.
2.3. Ao Ech (Frog Pond)
Situated deep within the core of Cat Ba National Park, Ao Ech, or Frog Pond, feels like a “paradise on earth.” It lies halfway along the 9-kilometer jungle trail connecting the park’s center to Viet Hai Village. True to its name, thousands of frogs live here, hiding among rocks and bushes during the day or colder months.
When night falls or rain begins, their croaks echo through the forest, blending with birdsong to create a unique symphony of the wild that can be heard from miles away. Perched about 100 meters above sea level, the crystal-clear pond mirrors the sky and the surrounding greenery. Beneath the surface lies a soft layer of silt and aquatic vegetation, while fish and freshwater crabs dart between rocks and roots. Ao Ech’s untouched charm, tranquil air, and natural harmony make it a serene highlight of the national park.
2.4. Viet Hai Fishing Village
Nestled deep within Cat Ba National Park, Viet Hai Fishing Village is a hidden gem where time seems to slow down. Visitors can reach Viet Hai by hiking through the forest or by boat through the scenic Lan Ha Bay, then cycle through pristine forest trails while enjoying birdsong and wildflowers along the way.
Surrounded by majestic mountains, dense forests, and emerald waters, this small village of around 100 households preserves its centuries-old charm and peaceful way of life. Here, you can walk through vast rice fields, enjoy a natural fish foot massage, admire thatched-roof houses made of earth, and savor local specialties like hill chicken, forest vegetables, and freshly caught seafood.
