Ha Long Bay is located in Quang Ninh Province, northeast of Vietnam. Ha Long Bay was recognized twice by UNESCO as a World Natural Heritage site in 1994 and 2000 with the value of natural landscape and geology and geomorphology. Spending watching the sun set over the calm waters of Ha Long Bay, and waking up to a serene morning surrounded by karsts. Relaxing on a sun deck surrounded by magnificent panoramas is the highlight of many a trip.
