7 Undiscovered Treasure Lagoons & Lakes in Vietnam for 2025

Thac Ba (Yen Bai)

Thac Ba lake located about 180 kilometers from Hanoi (a two-and-a-half-hour drive) is the first on the list of best lagoons and lakes in Vietnam. The national historical site, which is also referred to as “Ha Long Bay on the mountain”, has more than 1300 islets and grottos. It has been built through damming for hydroelectricity making it one of the largest man-made lakes in Vietnam. Thus, around it is lush green vegetation and forests bordered by it.

The lakeside complex has numerous outdoor activities like fishing, swimming and boating that one can participate in. All this while exploring within the caves on the isles lying within the lake complex. The region is populated by several ethnic minorities, with Ngoi Tu village being one of them which accommodate five different ethnic groups including Dao people providing visitors with an authentic experience. As a means towards greater cultural immersion also tourists could consider visiting local villages then proceed for an overnight homestay.

In addition, Thac Ba Lake is ideally paired with a visit to Vietnam's stunning rice fields, situated 200 km further in Mu Cang Chai within the same province of Yen Bai. Known for majestic rice fields in Vietnam, stunning views during the Water Pouring Season, and the famous paragliding festival in Khau Pha, Mu Cang Chai leaves a lasting impression on visitors.

Ba Be Lake (Bac Kan)

The second freshwater lake, Ba Be Lake, lies in Ba Be National Park in Bac Kan Province. Ba Be Lake is one of the largest natural freshwater lakes in Vietnam that can be found up north. Positioned 215 km from Hanoi, it would take you roughly four hours to drive and arrive at this beautiful place.

Do you know how “Ba Be” got its name? The phrase “Ba Be” translating literally as "three lakes," and this place indeed possesses three large, deep lakes that are connected through an area of 500 hectares. It was recognized as a tourist destination in May 1995 in Vietnam. So, make sure you set aside a day if you want to take advantage of everything that the park has to offer.

The surrounding ecosystem is diverse, creating a vivid and poetic natural setting. Hidden deep within majestic mountains and forests, the lake exudes serene beauty, perfect for picnicking, camping, and trekking.

The park is a sanctuary for various indigenous groups and a habitat for diverse wildlife, including mammals, insects, and birds. Its limestone mountains feature extensive cave systems, such as the 800-meter-long Hua Ma Cave, which boasts an impressive 50-meter-high ceiling.

Nearby, you’ll find Dau Dang Waterfall, also known as Ta Ken Waterfall. This stunning cascade flows through lush greenery, creating a breathtaking natural spectacle. With its scenic blend of lakes and mountains and easy access from major routes, Ba Be Lake and its national park are must-visit destinations. 

Hoa Binh (Hoa Binh)

When you think of Hoa Binh Province, Mai Chau Valley often comes to mind as a must-visit spot. Nearby, however, is Hoa Binh Lake, which shares its name with the province. This proximity makes it very convenient to explore both places in one trip, as they are only about a two-hour drive apart.

Hoa Binh Lake is a water storage facility used to supply the Hoa Binh Hydropower Plant, placed on the Da River, which stretches 230 km from Hoa Binh to Son La. With a capacity of up to 9.5 billion cubic meters of water, Hoa Binh Lake is regarded as the largest artificial lake in Vietnam.

Although it is an artificial lake, the lake is surrounded by mountains and lush forests, making it a paradise for nature lovers and anyone looking to unwind. The area is also rich in culture, with diverse ethnic groups like the Muong and Thai contributing their unique traditions, architecture, and vibrant markets to the natural beauty.

There's plenty to do around the lake. You can take a leisurely cruise, try kayaking or fishing, or simply relax by the lakeshore. For adventurers, hiking in the nearby hills offers incredible views of the lake and surrounding valleys.

Hoan Kiem (Hanoi)

Hoan Kiem Lake, also known as Sword Lake, is probably the most popular lake in Northern Vietnam and the entire country. Due to its location and the presence of two temples on the island, it is a must-visit spot for anyone. Ideally, it is recommended to visit the lake in the morning or afternoon to experience the hustle and bustle of residents jogging, walking, and chatting.

Besides this, Hoan Kiem Lake forms the political and social heart of Hanoi and Vietnam’s soul. In the morning, you will see people practicing tai chi, doing exercises, walking slowly, or jogging, creating a refreshing atmosphere with their breathing. At night, particularly in the evening, many people walk around while street vendors sell their wares, creating a colorful environment filled with lights. The area is vehicle-free on weekends, allowing visitors some freedom—something not easily found during regular days in busy Hanoi.

In the middle of the vibrant, red-colored edge of the lake lies Turtle Island, connected by the bright red Long Huc Bridge. On the island stands Turtle Tower, a memorial commemorating several Vietnamese heroes. This spot is a favorite for many tourists taking pictures in Hanoi.

Tam Giang Lagoon (Hue)

If other cities have gorgeous beaches and lakes that entice tourists, Hue's former capital has another piece of artwork: Tam Giang Lagoon. This lagoon is considered as the largest freshwater lagoon in Hue and an example of Vietnam's unique lagoon ecosystems. Tam Giang Lagoon spans approximately 52 km2, making it one of Southeast Asia's biggest freshwater lagoons.

Visitors can witness both the beauty of Tam Giang Lagoon and its local life forms. One could charter a boat for sightseeing purposes, participate in fishing activities alongside natives or support them Asian vegetables while soaking up the environment around that scenic water body.

You could also lend a hand to locals assisting them with household duties or alternatively sit down for a chat with their amiable residents. For example, after visiting the site during sun rise hours one could then depart towards Thai Duong Ha fishing village where he/she would witness busy activities at floating markets before ordering some sea foods freshly caught by local fishermen.

Ta Dung (Dak Nong)

Ta Dung is a vast reservoir within the Ta Dung Nature Reserve, based in the Central Highlands region of Vietnam, in Dak Nong province. This lake spans over 22,000 hectares. Across the hills and mountains of the Central Highlands, hydroelectric power stations have blocked rivers, creating large artificial lakes. What were once the peaks of hills and mountains are now submerged islands, giving the lake a resemblance to Ha Long Bay in the heart of Vietnam.

If you're looking for a great hiking destination, this is an ideal choice! Beyond the breathtaking mountain and lake views, the area offers a unique coolness from the highland air, lush nature, and refreshing breezes that blend seamlessly with the verdant surroundings.

At Ta Dung Lake, you can not only trek and enjoy the scenery, but also witness unparalleled sunsets as the sun’s rays reflect off the water. You could have breakfast while watching clouds drift above the lake, camp under the stars for a night in the dense forest or wake up in your tent to see the glorious dawn breaking through the surrounding foliage. There are also vegetable plots, flower gardens, and lush bamboo forests to explore. Alternatively, you can navigate the lake by boat, camp overnight on one of its many islands, or paddle along in the twilight when the fog blankets everything.

Lak (Dak Lak)

Lak Lake, stationed in the Central Highlands region like Ta Dung Lake, is the final spot in our top 7 list of the most beautiful lagoons and lakes in Vietnam. As the second-largest freshwater lake after Ba Be Lake (Bac Kan), Lak Lake is situated in Dak Lak Province, a land of vast forests with plenty of sunlight and wind. Despite its seemingly dry backdrop, the lake appears calm and pristine.

The Mnong tribe lives around this body of water and depends on it for their livelihoods; they can often be seen fishing from their traditional dugout canoes. Spanning an area of 500 acres, Lak Lake is surrounded by towering mountains covered with immense primeval forests that are home to diverse wildlife species. People are drawn to its natural beauty, which is enhanced by activities such as traditional wooden boat tours across the lake and hiking through lush surroundings.

Ancient forests skirt the lake, providing a habitat for many species, including some listed in the Red Book. Tame elephants are often seen nearby and are sometimes drawn to by tourists, with women riding elephants along the roads. These elephants are guided to ponds where they drink or bathe, as the rivers are deeper and less clear. It’s no wonder people enjoy visiting them so much!
