1. Introduction to Cat Ba Island

Among the 367 islands that comprise the Cat Ba Archipelago, Cat Ba Island stands out as the major and biggest. Cat Ba Vietnam is an iconic landmark for visitors to the area, about 45 kilometers east of Hai Phong City.

At approximately 26,000 acres, Cat Ba is the third biosphere reserve in Vietnam and is home to a rich variety of creatures. The island gained international recognition as a Biosphere Reserve Zone in 2004 when it was designated by UNESCO.

Its karst topography is what makes the Cat Ba landscape famous. Limestone mountains, beautiful caverns, and powdery white sand beaches are all features of the island's exceptional terrain.

Cat Ba Island is undoubtedly the island to visit if you are in the northern part of Vietnam. Expect at least 2 days to explore this captivating island because you'll find yourself delighted with a great array of fun and wonderful activities. Here are our picks on the best things to do in Cat Ba Island:

2. 10 Best Things to Do in Cat Ba Island

1.1 Play with water on Cat Co Beaches

One of the top things to do in Cat Ba on a hot summer day is to dive into the crystal-clear blue waters of Cat Ba Beach. 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 rent boats to take yourself to Monkey Island or Tung Thu Beach, where you can relax in the calm waters and take in the sights. The untamed beaches of Lan Ha Bay provide an opportunity for adventurers to get in touch with nature. Immersing yourself in the water here will undoubtedly be one of the most memorable experiences of your Cat Ba trip, whether you are seeking peace or excitement.

1.2 Explore Cat Ba island with a kayak

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 kayak tour or a cruise on Cat Ba Island 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.

1.3 Take a cruise tour in Lan Ha Bay

As we 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.

1.4 Try squid fishing on Lan Ha Bay

Nighttime squid fishing is one of the best activities in Cat Ba Island. If you're interested in giving it a go, you can either ask your hotel to arrange it or visit the town's main port to speak with the rafters and boat people. The seas come alive as the sun goes down, providing a once-in-a-lifetime opportunity to see the tranquil beauty of the night sea and maybe even reel in some squid. The second option is that if you book the cruise to Lan Ha Bay, there may be a night squid fishing tour available inside the itinerary. Please check in advance with your tour operator.

1.5 Watch the sunset while uncovering the history of Cannon Fort

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. Discover the incredible story of the Vietnamese victory and be amazed by the ability of this little nation to fire down American planes over the Gulf of Tonkin.

A motorbike, a vehicle, or even just a short stroll will get you to the fort. Every individual is charged 40,000 VND to enter the fort during its daily opening hours of 7 a.m. to 6 p.m. 

1.6 Trek through 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 and five different boat excursions 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.

1.7 Visit fishing villages

Make sure you stop by the Cai Beo fishing village while you're in Cat Ba. Although it isn't quite as busy as Lan Ha Bay pier, Ben Beo has a variety of vessels that may take you to Vietnam's oldest fishing town, 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 several houses allows you to peruse the seafood offerings, which range from conventional fare to more unusual and exotic varieties.

Another fishing village worth visiting is Viet Hai Village. The picturesque coastal community stretches out along the shore around 18 kilometers from Cat Ba town. Starting your hike from Cat Ba National Park and making your way past Frog Lake is one way to reach the town. Travelers visiting Viet Hai will be able to take in the picture-perfect landscapes, serene ambiance, and easygoing locals' way of life. Also, the people who work as farmers for the most part are quite welcoming. You can escape the hustle and bustle of the outside world at Viet Hai.

1.8 Go rock climbing

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.

1.9 Explore the caves

Unraveling the secrets of beautiful caverns is another interesting thing to do in Cat Ba Island. There are tales to be told in two of the most impressive, Hospital Cave and Trung Trang Cave. Constructed between 1963 and 1965, Hospital Cave served as a military hospital throughout the conflict. There is a cinema theater, therapy, and rehabilitation spaces, and 17 other rooms spread out across three stories. It was during that era that the bomb-proof door design was implemented.

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.
