Take advantage of the calm, clear waters and numerous small, sandy beaches hidden throughout Halong Bay, Lan Ha Bay, and Bai Tu Long Bay. Most overnight cruises will include opportunities for swimming Halong Bay or its neighbouring bays, often anchoring in quiet coves or near secluded beaches accessible only by boat or kayak.

Whether it's taking a refreshing dip off the side of your cruise boat, paddling to a tiny beach like Ba Trai Dao beach in Lan Ha Bay, or relaxing on the sands of Titov Island beach, enjoying the water is a quintessential part of the Vietnam bay cruise experience. The stunning backdrop of limestone karsts makes swimming here truly unforgettable.
