Nestled to the south of Ha Long Bay and enveloping the Cat Ba archipelago, Lan Ha Bay emerges as a “forgotten paradise,” boasting a pristine, tranquil beauty largely untouched by mass tourism. Spanning over 7,000 hectares, the bay is a colossal ink-wash painting brought to life by more than 400 islands, large and small. Each island is draped in a lush green carpet of vegetation, reflecting its image onto the crystal-clear emerald waters below.
The islands in Lan Ha Bay all feature charming little sandy beaches at the foot of their limestone mountains, creating countless private, secluded spots for a swim. This makes it the ideal destination for activities like kayaking, swimming, and soaking in the magical moments of a sunset. So, let’s join WISTARIA HOTEL as we share our guide to these unforgettable experiences.
Cat Ba Kayaking: A Journey to Touch Every Corner of the Bay
Kayaking is more than just a sport; it’s the absolute best way to freely weave through the most beautiful hidden corners of Lan Ha Bay, places where large cruise ships cannot reach. The feeling of paddling on the calm water, gliding through mysterious caves, and setting foot on a deserted, footprint-free beach is a truly unforgettable experience.
The Most Beautiful Kayaking Spots in Lan Ha Bay:
- Monkey Island (Đảo Khỉ): This is the perfect choice for beginners or families with young children. The waters around the island are quite calm and close to the shore. You can paddle while watching the mischievous monkeys on the island, and then combine it with a climb to the summit for a panoramic view of Lan Ha Bay.

- Bright Cave – Dark Cave (Hang Sáng – Hang Tối): This is the “specialty” of the region. Experience kayaking through a pitch-black grotto, guided only by the light from your headlamp and the sound of your paddle, only to emerge, breathless, into a hidden lagoon completely encircled by majestic limestone cliffs. The serene and isolated space inside will make you feel as if you’ve entered another world.

- Viet Hai Ancient Fishing Village (Làng Chài Cổ Việt Hải): Kayaking to Viet Hai village is a unique cultural discovery. The waterway leading to the village passes through peaceful waters, flanked by pristine natural landscapes. Upon arrival, you can park your kayak and cycle deeper into the village to learn about the peaceful life of the local fishing community that has lived here for generations.
- Ba Trai Dao Area (Three Peaches Area): This is an archipelago of three small islands shaped like three peaches. Kayaking around this area not only offers beautiful scenery but also allows you to stop at the romantic Ba Trai Dao beach to rest and swim in its crystal-clear water.

Tips for Kayaking in Cat Ba:
- What to Bring?: Always carry a waterproof bag for your phone and camera, sunscreen, a wide-brimmed hat, sunglasses, and a bottle of drinking water.
- Where to Rent Kayaks?: You can rent them directly at Ben Beo Pier, on cruise ships (often included in the tour price), or at some floating tour operators. The rental price ranges from 50,000 – 100,000 VND per kayak per session.
- Basic Technique: Sit with your back straight and your feet comfortable. When paddling, use the rotational force of your entire upper body rather than just your arms to avoid fatigue. Start practicing in shallow, calm water to get accustomed to it.
- Safety First: Always wear a life vest, no matter how well you can swim. Listen carefully to your guide’s instructions. Do not stray from the group, paddle too far from the shore, or enter areas with danger warnings or whirlpools. Check the weather forecast before you go.
Swimming in Cat Ba: Immerse Yourself in the Cool, Refreshing Water
Cat Ba is home to many famous and beautiful beaches, from the bustling ones near the town center to the pristine, secluded coves within the bay.

Top Can’t-Miss Beaches in Cat Ba:
- Cat Co Beaches (1, 2, 3): This trio of beaches is the most famous and is located near the town center. Cat Co 1 is the most spacious and lively. Cat Co 2 is smaller, quieter, and more romantic. Cat Co 3 is modern with plenty of services. The three beaches are connected by a beautiful wooden bridge that winds along the mountainside.
- Tung Thu Beach: Located about 2km from the center, this is a well-planned, clean beach with very gentle waves and a graceful crescent shape. It is highly suitable for families with young children.
- Ba Trai Dao Beach: A stunning beach in Lan Ha Bay that boasts shallow, crystal-clear water where you can see right to the bottom. It’s an ideal place for swimming and relaxation.
- Van Boi Beach: A small, pristine, and extremely quiet beach. The water here is clear and clean, with fine sand. It is a favorite stop for cruise ships, offering tourists a chance to feel truly close to nature.

Important Notes for Swimming in Cat Ba:
- Beaches like Ba Trai Dao and Van Boi are heavily affected by the tide. At high tide, the sandy beach can be completely submerged. Ask your guide or a local to find the best time to visit.
- Do not swim too far from the safe zone, especially on days with strong waves. Be cautious of jellyfish, which can appear at certain times of the year.
Watching the Sunset over Lan Ha Bay: A Masterpiece of Nature
The sunset over Lan Ha Bay is reputed to be one of the most spectacular sights in Northern Vietnam. As the sun slowly dips behind the endless limestone karsts, the entire sky and sea are painted in magical hues of orange, pink, and purple before fading into night.

The Best Ways to Enjoy the Sunset:
- Sunset Party Cruise: This is the most popular and comprehensive option. Half-day cruises often combine kayaking, swimming, and a light afternoon tea party right on the sundeck for you to enjoy the sunset.
- Cannon Fort (Pháo Đài Thần Công): From this vantage point, you can enjoy a panoramic view of the Cat Ba archipelago and Lan Ha Bay from above. The moment the sun sets from here is majestic and breathtaking.
- On a Kayak in the Middle of the Bay: If you are an experienced kayaker, sitting on a kayak, floating in the middle of the bay, and feeling the absolute tranquility as dusk falls is an exceptionally special experience.

Suggested Sunset Tour Itinerary:
- 3:00 PM: A shuttle picks you up from your hotel in Cat Ba town center and transfers you to Ben Beo Pier.
- 3:30 PM: Board the cruise, enjoy a welcome drink, and begin your journey to explore the bay.

Lan Ha Bay and Cat Ba Island are not just a destination, but a journey of emotions—from the thrill of conquering the bay’s nooks and crannies on a kayak, to the relaxation of immersing yourself in cool water, to the profound peace of witnessing a magnificent sunset.
