Hạ Long Bay, located in the Quảng Ninh Province of Vietnam, is a stunningly beautiful destination. Here, towering limestone pillars and tiny islands topped by rich, green forests rise from the waters of the Gulf of Tonkin. Halong translates as 'where the dragon descends into the sea' and local legend suggests that this seascape was created when a great mountain dragon charged towards the coast, its flailing tail gouging out the valleys and crevasses in its path.
