Lan Ha Bay sits just east of Cat Ba Island and is known for its limestone islands, calm waters, small beaches, and sheltered coves. While it shares the same karst landscape as Ha Long Bay, Lan Ha often feels more focused on outdoor activities and time around Cat Ba Island.

For travelers who enjoy kayaking, swimming, island activities, and a more active cruise experience, Lan Ha Bay is a great alternative to the classic Ha Long Bay route.

Things to do in Lan Ha Bay

1. Stay overnight on a Lan Ha Bay cruise

An overnight cruise is one of the easiest ways to experience Lan Ha Bay without rushing between different places. You can spend the day exploring the bay, then return to the boat to relax and enjoy the scenery from the deck. Many cruises also include activities such as morning Tai Chi and cooking demonstrations.


2. Kayak through hidden lagoons

Kayaking is one of the highlights of Lan Ha Bay. The sheltered waters are generally calm and suitable for beginners, while the limestone formations create plenty of interesting routes. Depending on the itinerary, you may paddle through small lagoons, around limestone cliffs, or through narrow openings that larger boats cannot reach.


3. Swim and relax at quiet beaches

Lan Ha Bay has many small beaches tucked between the limestone islands. Ba Trai Dao Beach and Van Boi Beach are popular spots for swimming and relaxing when conditions allow. Some cruise itineraries include a beach stop, although the exact location can change depending on tides and weather.


4. Explore Cat Ba Island and Viet Hai Village

Lan Ha Bay is closely connected with Cat Ba Island, giving you the chance to add some land based experiences to your trip. Some itineraries include Viet Hai Village, where you can cycle through the countryside, see local homes and farms, and experience a quieter side of island life.


5. Try a little adventure around Cat Ba

For travelers looking for something more active, areas around Cat Ba Island also offer rock climbing, snorkeling, and diving. Rock climbing and deep water solo climbing can be found around places such as Butterfly Valley, while snorkeling and diving are possible in suitable areas with clearer water. These activities depend on weather and sea conditions and should be arranged through experienced or certified operators.
