Why Visit Cat Ba Island?
Cat Ba Island is the largest island in northern Vietnam’s coastal waters, where lush subtropical landscapes meet dramatic limestone karsts and pristine seascapes. Travelers select Cat Ba over standard mainland resort areas because it allows direct access to both sea activities and deep rainforest trekking within a single visit.
Where Is Cat Ba Island Located?
Cat Ba Island lies approximately 30 km east of Hai Phong City center and about 150 km southeast of Hanoi. Administratively belonging to Hai Phong City, the island sits adjacent to Halong Bay, sharing the same geological karst landscape while maintaining separate administrative oversight and quieter parts of the bay with fewer boats
What Makes Cat Ba Island Worth Visiting?
The island features over 17,000 hectares of protected land and marine territory designated as a UNESCO Biosphere Reserve. Visitors can explore deep limestone caves, cycle through secluded coastal villages, hike primary forests home to rare Cat Ba langurs, and kayak around serene emerald lagoons away from major commercial shipping routes.
Best Time to Visit Cat Ba Island
Spring (March to May) and autumn (September to November) deliver mild temperatures, clear skies, and calm sea conditions suitable for outdoor trekking and cruising. Summer (June to August) brings warm temperatures and bright sun suited for swimming, though domestic visitor numbers peak on weekends. Winter (December to February) brings cooler breezes and lower rainfall, making forest hikes pleasant.

1. Cruise Through Lan Ha Bay
Lan Ha Bay stretches across more than 300 limestone islands just south of Halong Bay, known for its calm waters, secluded scenery, and relatively pristine ocean environment. Booking a private day trip or overnight journey provides a relaxed vantage point to observe towering cliffs and calm sea channels.
Explore Limestone Islands and Hidden Lagoons
Unlike the heavy boat traffic found in central Halong Bay, Lan Ha Bay features narrow passages between limestone pillars covered with thick green vegetation. Vessels navigate calm waters toward secluded coves like Ba Trai Dao and Van Boi, where small sandy beaches appear during low tide cycles.
Try Kayaking and Swimming in the Bay
Cruising allows guests to anchor near sheltered lagoons for swimming and self-guided kayaking. On our scheduled Lan Ha bay cruises, travellers receive safety instructions and life jackets before paddling through natural limestone arches and into peaceful lagoons that larger boats simply can’t reach.

2. Explore Cat Ba National Park
Covering approximately 17,360 hectares across land and marine zones, Cat Ba National Park preserves rare subtropical flora and fauna. Hiking inside the reserve allows travelers to understand the island unique ecological balance while traversing established forest trails.
Hike Through Tropical Forests
The park offers trails varying in difficulty, from paved paths to steep limestone ascents under canopy cover. Travelers can visit the Kim Giao forest, known for its indigenous hardwood trees whose timber was historically used to test food for royal dining.
Discover Wildlife and Scenic Viewpoints
The national park provides sanctuary to over 32 species of mammals and 70 bird species, including the critically endangered golden-headed langur. When arranging Trips to Cat Ba island, our private guides help navigate the terrain safely while pointing out local botanical species and viewpoints.

3. Relax at Cat Co Beaches
Located within walking distance of Cat Ba Town, the three Cat Co beaches (numbered 1, 2, and 3) provide sandy shorelines flanked by steep limestone islands. A constructed cliffside walk links all three coves, offering panoramic views of the outer bay.
Cat Co 1, Cat Co 2, or Cat Co 3: Which Beach Should You Choose?
Cat Co 1 is the largest cove, featuring wider sands and nearby beverage kiosks. Cat Co 2 offers a more compact, quieter setting surrounded by green hills, making it popular for reading and relaxing. Cat Co 3 provides modern resort facilities and deeper waters suitable for swimming during high tide.
Best Time for Swimming and Sunbathing
For calm water and comfortable temperatures, visit between May and October. Morning hours before 10:00 AM and late afternoons after 4:00 PM offer the best conditions to avoid midday sun during your Vietnam Holidays.

4. Go Kayaking Around Hidden Caves and Lagoons
Kayaking is the most effective method to reach low-clearance sea arches and closed lagoons across the Cat Ba Archipelago. Paddling alongside towering karst cliffs gives travelers a closer look at the marine life, vegetation, and striking limestone formations around them.
Explore Dark and Bright Cave
The Dark and Bright Cave (Hang Sang Toi) sits on the border of Halong Bay and Lan Ha Bay. Travelers paddle small kayaks or take local bamboo rowboats through a natural 100-meter tunnel that opens into an enclosed circular lake surrounded by vertical cliffs.
Paddle Through Peaceful Floating Villages
Kayaking near calm floating fishing villages gives travelers a quiet view of fish aquaculture cages and wooden boat docks. Our team recommends wearing safety jackets at all times and maintaining a safe distance from working aquaculture nets.

5. Visit Viet Hai Ancient Village
Viet Hai is a secluded rural community positioned in a central valley inside Cat Ba National Park. Accessible primarily by boat through Lan Ha Bay or via a multi-hour mountain trek, this community still preserves its traditional farming and fishing way of life.
Cycle Through the Island’s Peaceful Countryside
From Viet Hai pier, a paved 5 km road winds through limestone rock tunnels, past rice fields, and along mountain slopes into the village center. Bicycles and electric carts provide convenient transport options along this flat, scenic route.
Experience Local Life Away from the Tourist Crowds
In the village, travelers can observe traditional clay-walled thatched houses, visit herbal gardens, and sample local fish massage pools fed by natural mountain springs. The quiet environment contrasts sharply with busier commercial hubs on the mainland.

6. Take the Scenic Walk to Cannon Fort
Cannon Fort sits atop a hilltop overlooking Cat Ba Town at an altitude of 177 meters above sea level. This vantage point provides panoramic views across Lan Ha Bay, the coastal town, and surrounding karst peaks.
Enjoy Panoramic Views of Cat Ba Island
The observation platforms at Cannon Fort afford clear lines of sight over Cai Beo port and offshore floating villages. Photographers frequently visit this hilltop in late afternoon to document changing light across the archipelago.
Learn About the Island’s Wartime History
Built in the 1940s, the fort retains original heavy artillery cannons, underground concrete bunker complexes, and trench networks utilized during historical conflicts. Walking through the tunnels offers direct insight into the military history of the Gulf of Tonkin.

7. Explore Cai Beo Floating Village
Cai Beo is among the oldest and largest coastal floating communities in Cat Ba island, with archaeological artifacts dating prehistoric habitation back over 7,000 years. Located just 2 km from Cat Ba Town center, the village comprises approximately 300 floating households.
Discover One of Vietnam’s Oldest Floating Communities
The village consists of interconnected wooden houses resting on plastic barrels and wooden rafts. Families have maintained fishing and fishing cultivation traditions across generations, creating a self-sustaining aquatic settlement protected by surrounding karst rocks.
See How Local Fishing Families Live on the Water
Taking a small tender or rowing boat from Ben Beo pier through the village channels allows visitors to observe daily activities, including net repairing, fish feeding, and seafood market trading. Travelers booking Tours to Cat Ba island can stop here before boarding larger cruise vessels.

8. Trek or Hike to Ngu Lam Peak
Ngu Lam Peak is one of the most accessible and rewarding mountain summits inside Cat Ba National Park. The trail takes approximately 45 to 60 minutes one way from the park headquarters, leading through stone stairs and natural forest paths.
Follow the Forest Trail Through Cat Ba National Park
The route begins on paved paths before converting to limestone rock steps under dense tree canopy. Sturdy walking shoes with reliable grip are recommended, as limestone surfaces become slick following light morning mist or seasonal rain.
Enjoy Panoramic Views from the Summit
At the peak observation pavilion, hikers gain a 360-degree perspective over forested karst ridges rolling toward the distant coastline. This trek demonstrates the rugged geological diversity of northern Vietnam.
