Top Things to Do Halong Bay Cruise — Must-Try Activities
The undisputed highlight for most travelers. Paddle through Luon Cave’s narrow tunnels surrounded by towering karsts and emerge into hidden lagoons teeming with wildlife. No experience needed — guides provide instructions and safety equipment.
Available on: All our cruises — Premium, Sea Lion, Tropical, Grand
2. Exploring Sung Sot (Surprise) Cave
One of the largest and most spectacular caves in Halong Bay. The name “Surprise” is well-earned — the cave opens into a massive chamber with dramatic stalactites and stalagmites illuminated by colored lighting. A moderate climb of about 100 steps leads to the entrance.
3. Climbing Titov Island Viewpoint
Named after a Soviet cosmonaut who visited in 1962, Titov Island offers the most iconic panoramic view of Halong Bay. Climb approximately 400 steps to the summit for a 360-degree vista of hundreds of limestone islands stretching to the horizon. The beach below is perfect for swimming.
4. Swimming in Emerald Waters
Halong Bay’s warm, calm waters (25-30°C in summer) are ideal for swimming. Designated swimming areas near Titov Island and secluded Lan Ha Bay beaches offer clean, sheltered spots. The Sea Lion’s onboard Jacuzzi adds another dimension for water lovers.
among all things to do Halong Bay cruise activities.
5. Watching Sunset from the Sundeck
As the sun drops behind the karsts, the bay transforms into a golden canvas. Every cruise includes a sunset party on the sundeck with cocktails and snacks. On overnight cruises like Cozy Bay Grand, this is followed by a 5-course dinner — truly magical.
6. Squid Fishing at Night
Overnight cruises only. After dinner, the crew sets up fishing equipment and drops lights into the water to attract squid. It’s surprisingly exciting when you get a catch — the kitchen will even cook your catch for a midnight snack!
7. Sunrise Tai Chi
Overnight cruises only. Start your morning with a gentle tai chi session on the sundeck as the sun rises over the bay. Led by the cruise guide, this peaceful activity is suitable for all fitness levels and provides a uniquely serene experience.
8. Cooking Class
Select overnight cruises. Learn to make Vietnamese spring rolls or other local dishes from the onboard chef. A fun, hands-on activity that gives you a delicious souvenir skill to bring home. Usually held before dinner.
9. Visiting Floating Fishing Villages
On Tropical Cruise (Lan Ha Bay), you’ll visit authentic floating fishing villages where families have lived on the water for generations. Learn about their daily life, see floating fish farms, and understand the unique culture of Halong Bay’s maritime communities.

Halong Bay is a photographer’s paradise at every hour. The best light is during golden hour (sunrise/sunset), but the misty mornings of spring and winter create equally stunning, moody compositions. Key photo spots: Titov Island summit, kayaking in Luon Cave, sunset from the sundeck.
