1. Introduction to Cat Ba Island

Cat Ba Islands, located about 45 kilometers east of Hai Phong City, serves as a scenic counterpart to the world-renowned Ha Long Bay. Among the 367 islands that make up the Cat Ba Archipelago, Cat Ba Island stands out as the largest and most prominent. While Ha Long is famed for its majestic bay cruises, Cat Ba offers a more tranquil, off-the-beaten-path alternative with equally stunning limestone landscapes and coastal charm.

Long before Cat Ba became a paradise for beach lovers and nature enthusiasts, it was home to prehistoric communities. Archaeological discoveries have revealed traces of human settlement dating back 6,000 years, with ancient people once living in caves like Trung Trang, Thien Long, and Quan Y. Among these finds, the Cai Beo culture, unearthed in the nearby Cai Beo fishing village, is one of the oldest known coastal cultures in Vietnam, dating back around 5,000 years. These remnants offer compelling evidence of a long-standing tradition of fishing and settlement on the island.

Spanning approximately 26,000 acres, Cat Ba Island was recognized by UNESCO as a World Biosphere Reserve thanks to its exceptional biodiversity across lush forests, rare wildlife, marine areas, caves, and other ecosystems. It is the third biosphere reserve in Vietnam and is home to many rare species, including the Cat Ba white-headed langur.

What truly sets Cat Ba apart is its dramatic karst terrain—towering limestone cliffs, hidden caves, jungle-covered hills, and white-sand beaches. This unique topography creates a breathtaking backdrop for kayaking, trekking, rock climbing, and cruising around the untouched beauty of Lan Ha Bay.

Whether you’re planning a weekend escape or a longer coastal adventure, Cat Ba Island offers a perfect mix of exploration and relaxation. It's a paradise for eco-tourism. Keep reading for our curated list of the top things to do on Cat Ba Island to make your trip truly unforgettable.

2. Top 10 Best things to do in Cat Ba Island

2.1. Relax at Cat Ba Beaches

One of the top things to do in Cat Ba on a hot summer day is to dive into the cool clear blue waters of Cat Ba Beaches.

Pretty close to the center of town on Cat Ba Island are three beaches: Cat Co 1, 2, and 3. Golden sand beaches, blue ocean, and a plethora of tourist facilities, including electric vehicles, food and drink, and beachfront activities, make for spectacular beaches. You may find water activities at Cat Co 1 and 2. Popular Cat Co beaches may become rather busy, so it's better to swim in the early morning.

In case you want a new and quiet place to swim, there are a few hidden gems. You may want to take yourself to Monkey Island or Tung Thu Beach, where you can relax in the calm waters and take in the sights. Besides, the untamed beaches of Lan Ha Bay provide an opportunity for adventurers to get in touch with nature. Surrounded by limestone islets and lush jungle, these hidden stretches of sand are accessible only by boat, making them ideal for those looking to explore off-the-beaten-path destinations. Immersing yourself in the water here will undoubtedly be one of the most memorable experiences.

2.2. Kayaking in Lan Ha Bay

Kayaking is an adventure you shouldn't miss if you enjoy water sports. Lan Ha Bay is the king of Cat Ba kayaking spots, and for good reason: it's filled with stunning caverns, islands, and karsts. With its serene waters and pristine pathways, Lan Ha Bay is an ideal place to go kayaking for an afternoon or a whole day.

On Cat Ba Island, you have the option to arrange for your kayak rental or sign up for a half-day or full-day kayaking excursion. If you are new to the place and don't know where to go, we suggest that you book a Cat Ba Island cruise which already includes the kayaking part. However, there may be some restrictions on the amount of time you row compared to solo kayak because you are paddling in a group.

2.3. Discover Viet Hai & Cai Beo fishing villages

While you're in Cat Ba, you can visit the Cai Beo fishing village. Although it isn't quite as busy as Lan Ha Bay pier, Ben Beo pier has a variety of vessels that may take you to Vietnam's oldest fishing village, where you can enjoy the peaceful beauty of the waterways. Cruises on larger boats are great for large groups, but nothing beats a smaller boat for a more intimate view of the shore. Sail over the picturesque waterways of Cai Beo as the boatman relates fascinating tales from the village's past.  Stopping at various floating houses, you'll have the chance to browse their seafood selections—ranging from traditional favorites to more exotic, unusual varieties.

Another fishing village worth visiting is Viet Hai Village, a picturesque coastal community located about 18 kilometers from Cat Ba Town. Travelers visiting Viet Hai will be treated to a peaceful landscapes, a tranquil atmosphere, and a glimpse into the simple, welcoming lifestyle of the local residents, who are primarily farmers. It’s a peaceful escape from the hustle and bustle of the outside world—an ideal spot to slow down and reconnect with nature.

One way to reach it is by hiking through Cat Ba National Park, passing scenic spots like Frog Lake along the way. Alternatively, you can take a boat to Viet Hai Pier and then enjoy a leisurely bike ride through the countryside to the village.

2.4. Try night squid fishing

Night squid fishing is one of the most unique and enjoyable activities on Cat Ba Island. If you're interested in giving it a try, you can either ask your hotel to arrange the experience or head to the town’s main port to connect with local fishermen and boat operators. As the sun sets, the sea comes alive, offering a once-in-a-lifetime chance to witness the tranquil beauty of the night ocean—and, with a bit of luck, catch some squid yourself.

Alternatively, if you’re booking a Lan Ha Bay cruise, check whether a night squid fishing tour is included in the itinerary.

2.5. Take a cruise tour around Lan Ha Bay

As mentioned earlier, a boat cruise is a perfect option if you are unsure of what to see and where to go on this beautiful island. If you're looking for an alternative to the rather touristy Halong Bay boat trip, an overnight voyage across Cat Ba is a great choice. Lan Ha Bay is a little-known treasure on Cat Ba Island. It's surrounded by serene, verdant seas and has hundreds of islands and rocky limestone structures. The pristine bathing places and less-trafficked kayaking locations are the selling points of a boat trip.

Cat Ba Island offers a wide variety of ship cruises, much like Halong Bay. Day cruises, 2-day, and 3-day itineraries are all available for you to choose. Your vacation's preference, as well as the kind of cruise, schedule, activities, facilities and budget will determine which cruise is suitable.

2.6. Trek in Cat Ba National Park

The national park on Cat Ba Island, similar to that on Phu Quoc Island, provides excellent chances for climbing and trekking. The UNESCO Cat Ba Archipelago Biosphere Reserve, which encompasses over half of the island, is home to hundreds of species of birds, animals, and plants, including flora and fauna. Six distinct ecosystems—a tropical rain forest, a mangrove forest, a tidal flat, a marine lake, coral reef, and a soft bottom—are scattered throughout the park.

Up to nine different hiking routes in Cat Ba National Park are at your service. The route between Kim Giao and Ngu Lam Summit is popular among young, daring people. The trail is approximately 1 kilometer in length, and Ngu Lam Peak stands at 220 meters. There is a 700-meter ascent to Kim Giao Peak, which is 300 meters distant. Hikers seeking a strenuous journey will love the path that begins at Frog Pond and ends at Viet Hai Village. Embark on a thrilling five-hour journey amid verdant underbrush, slick rocks, and parched leaves. The Trung Trang Cave – Quan Y Cave trek is a great option for those looking for a less strenuous hike that yet takes in the stunning scenery of the park. Getting a feel for the park's atmosphere without the exertion is possible.

2.7. Visit Cannon Fort for sunset and history

Cannon Fort, with its breathtaking views of Lan Ha Bay and the islands in the distance, is a favorite spot for visitors to Cat Ba to enjoy a sunset viewing. Its prime location on a strategic hill allows for breathtaking views in all directions, but notably at dawn and dusk. 

However, few visitors are aware that this fortress has a history that stretches back to the War Period and other conflicts fought between Vietnam and the West in the twentieth century. Invaded by the Japanese during WWII, the island served as a prime vantage point for naval and aerial assaults. The guns and other infrastructure were linked by an intricate network of tunnels and ditches that they dug underground. After that, the Vietnamese utilized Cannon Fort as a stronghold during the American and French conflicts. There is a striking similarity between Cannon Fort and Ho Chi Minh City's Cu Chi Tunnels. Travelling here with a local tour guide, you can discover the incredible story of the Vietnamese victory and be amazed by the ability of this small nation to fire down American planes over the Gulf of Tonkin.

2.8. Go rock climbing in Lan Ha Bay

Rock climbing and Lan Ha Bay go hand in hand. Cat Ba has grown in popularity as a place to go rock climbing and relax due to its pleasant climate, stunning beaches, and primary forests.

Rock climbers can find a variety of challenges that suit their skill level on the several islands. Beo Wharf is the starting point for five different rock climbing routes. From there, you can take a boat offshore and conquer several picturesque cliffs in the area. Among them, the most favorite cliffs are located on Dau Be, Van Boi, Fish Cave, and Tien Ong islands.

If you decide to join in this adventurous activity, put safety first and find a reliable company to be your companion. Climbing gear is available for hire, but a qualified guide is a good idea if you're not an expert. You can trust them to keep you secure while you enjoy yourself.

2.9. Explore Cat Ba caves

Exploring the island’s fascinating caves is another interesting thing to do in Cat Ba Island. Two of the most impressive are Hospital Cave and Trung Trang Cave, each with its own unique story to tell.

Constructed between 1963 and 1965, Hospital Cave served as a military hospital throughout the conflict. The structure spans three levels and includes a cinema, therapy and rehabilitation rooms, and 17 other chambers—an impressive feat of wartime engineering. Notably, its bomb-proof door design made it a safe haven during air raids.

The 300-meter-long Trung Trang Cave is located in the other way and cuts through the mountainside. Entering a realm of dazzling structures formed by trickling water over six million years will astound you. Not to mention the amazing variety of stalactites and stalagmites. The ancient Vietnamese artifacts found in the cave further enhance its charm.

2.10. Taste the fresh seafood

The seafood feast is a must-do for travelers visiting Cat Ba Island. Clams, lobster, snapper, and a plethora of other delicious selections are available. These delectable delicacies are available in Cat Ba Market or may be enjoyed at one of the restaurants' grilled, stir-fried, or steamed options. You may sample a unique eating experience by dining on rafts near the sea. Picture this: you're eating seafood while basking in the ocean wind; it's more than just food; it's an entire island experience. Here are some great restaurants to try seafood:

• Vien Duong Restaurant at 12 Nui Ngoc, Cat Ba Island 
• Marigold Restaurant Cat Ba at 174 1/4 Street, Cat Ba Island
• Bien Dong Restaurant at No. 8, Nui Ngoc Street, Cat Ba Island
• Hai Yen Restaurant at No. 238, 1/4 Street, Cat Ba Island
• Quan Cat Ba Restaurant at No. 195, Street 1/4, Cat Ba Island

3. What is the best time to visit Cat Ba Island?

The best time to visit Cat Ba Island is from April to June and September to November. During these months, the weather is pleasantly mild, with lower humidity, calmer seas, and clearer skies, ideal for beach activities, boat cruises, kayaking, and hiking in Cat Ba National Park.

Summer (June to August) is also a popular time for domestic tourists, but it can be hot, humid, and crowded, with occasional heavy rains or storms.

Winter (December to February) is cooler and quieter, making it a good option if you prefer fewer crowds. Though the sea may be too cold for swimming and foggier, which can limit visibility for boat tours.

Meanwhile, visiting Cat Ba in the fall or spring means fewer tourists, smoother ferry rides, and ideal conditions for exploring Lan Ha Bay. With nature in full bloom and the island’s limestone landscapes bathed in soft light, these months offer a perfect balance of tranquility and adventure.

To enjoy the best mix of good weather and fewer tourists, consider visiting in May or late September.
