Discover a world of my mystical grottoes, ancient islets, pure beaches, and floating villages when you take off over the beautiful emerald of Ha Long Bay. Situated in the northeast region of Vietnam, Halong Bay is part of Bac Bo Gulf and comprises the sea area of Halong City, Cam Pha Town and a part of Van Don island district, Quang Ninh Province. It borders Cat Ba Island to the south-west, the mainland to the West, with a 120km-long coastline. Designated a Unesco World Heritage site in 1994, this mystical landscape of limestone islets is often compared to Guilin in China or Krabi in southern Thailand. In reality, Halong Bay is more spectacular. It covers a total area of 1,553km², including 1,969 islands of various sizes, 989 of which have been given names. There are two categories; limestone and schist, which are concentrated in two main zones: the southeast (belonging to Bai Tu Long Bay) and the south-west (belonging to Halong Bay). The average geological age of the islands is between 250 and 280 million years old. Halong Bay has been called by the great national poet Nguyen Trai: \" a marvel of the earth erected towards the high skies\". While exploring the bay, visitors step back in time amidst the legendary world of ancient islands. Many have adopted names to describe their shapes and forms such as Hon Dau Nguoi (Human Head Islet), Hon Rong (Dragon Islet), Hon Canh Buom (Sail Islet), Hon Trong Mai (Cock and Hen Islet) … However, the beauty of Halong Bay does not consist only in the forms of its mountains, but also in its infinitely rich system of grottoes and caves such as Thien Cung (Heavenly Palace Grotto), Dau Go (Driftwood Grotto), Sung Sot (Surprise Grotto), Tam Cung (Three Palace Grotto), Trinh Nu (Virgin Grotto) … and more.
