Quick Summary: Ba Trai Dao (Three Peaches) is a group of three peach-shaped limestone islets in Lan Ha Bay with several small, sheltered beaches. Some of the beaches are covered at high tide while others stay above the water. The area is reached only by boat on a Lan Ha Bay cruise or day tour.
Ba Trai Dao Beach is a cluster of three small limestone islets in Lan Ha Bay, Vietnam, located in the quieter southern part of the bay near Cat Ba Island. The calm, clear water and small sandy beaches make it a regular stop for swimming, kayaking and jumping from the boat, with no road access from the island.
What makes Ba Trai Dao Beach different?
Ba Trai Dao is an offshore stop that can only be reached by boat, unlike the beaches near the town of Cat Ba Island. The islets have no roads, no beach bars and no shops, only three limestone hills around a sheltered area of calm green water. The name means "Three Peaches", after the rounded shape of the islets seen from the water.
- Clear water: the water around the islets is clear enough for swimmers to see small coral and marine life just below the surface.
- Tide-dependent beaches: the size of each beach changes with the tide, so the crew chooses the beach with the most sand at the time of the stop.
Beka Insight (GPS location): Ba Trai Dao is located at approximately 20.7905° N, 107.1003° E. Standard map apps do not mark a boat dock for this part of the bay, so Beka captains use these coordinates from their own route logs for planning.
Long-term observation at Hon Dau puts average waves in this part of the gulf at 0.8 to 1.2 meters. Several layers of islands screen the bay from the open sea. The three hills at Ba Trai Dao add one more layer of shelter, which keeps the water calm for swimming on most days.
Is Ba Trai Dao Beach covered at high tide?
Ba Trai Dao has several small beaches, and some of them are covered at high tide while others stay above the water all day. The tide in the Gulf of Tonkin rises and falls once a day, with a range of three to four meters. This changes the shape of each beach between morning and afternoon.
The largest area of sand appears in the hours around low tide, when the smaller beaches between the islets also come out of the water. Beka crews check the tide table each day and choose the beach that offers the best swimming conditions at the time of the stop.
How do you get to Ba Trai Dao Beach?
Ba Trai Dao can only be reached by boat, because there is no road or public ferry to the islets. The usual way to visit is on a Lan Ha Bay day tour or an overnight cruise that includes the beach in its route.
- Standard stop: most tours spend 30 to 45 minutes at Ba Trai Dao for swimming and jumping from the boat, usually after kayaking through caves and lagoons in the morning.
- Boat-only access: without road access, the number of visitors stays limited, and the beaches remain quieter than the beaches near Cat Ba town.
Once ashore, visitors find a curved sandy beach below limestone cliffs covered in green trees, with calm water sheltered by the three islets. Kayaking around the base of the islets is a common activity before or after swimming.

What other beaches are near Ba Trai Dao?
Van Boi Beach is a second quiet beach in Lan Ha Bay that combines well with Ba Trai Dao on the same trip. The beach is located at the base of a steep limestone cliff and is a common starting point for kayaking through the small bays behind it.
Both beaches are far from the busy beaches on the main island and have no shops or facilities. Travelers with extra days can compare more options among the Cat Ba beaches, from town beaches to small beaches that local captains know by name.
Can you camp overnight on Ba Trai Dao Beach?
Camping on Ba Trai Dao Beach is not offered, because tour boats use the islets as a short daytime stop rather than an overnight anchorage. Some of the beaches are also covered at high tide, which makes an overnight stay on the sand unsafe.
Travelers who want a night close to nature can choose a Lan Ha Bay overnight cruise with a private cabin on the boat. Another option is a jungle bungalow in Viet Hai Village, which is part of the Lan Ha Bay 2 Days 1 Night Adventure.
