Halong Bay is one of Mother Earth’s most amazing natural wonders and one of Vietnam’s most prized treasures. A comfortable 3 hours drive from Hanoi, Halong Bay is in Northeastern Vietnam on the shores of the Gulf of Tonkin. The bay is dominated by more than 1,600 limestone karsts and islets which rise out of the waters of the bay to heights of up to 100 meters (330 feet) and the numerous caves and grottos spread throughout the bay. Abundant scenic beauty, archeological and geological significance, cultural and historical connections, fresh seafood and proximity to international gateways make Halong Bay one of Vietnam’s most popular places to visit.
