For travelers planning a Vietnam trip package, Halong Bay stands out as a surreal seascape and a true natural wonder. “Hạ Long” means “Descending Dragon,” tied to a legend where dragons were sent by the Jade Emperor to protect Vietnam. Their descent created valleys and limestone formations that now define the bay’s ethereal landscape.

Recognized by UNESCO in 1994, Halong Bay is a geological marvel of over 1,600 limestone karsts spread across nearly 1,500 km². These formations have developed over 500 million years, forming dramatic caves, arches, and grottoes. As one of the most photographed spots in Southeast Asia, it continues to be a core highlight of many best Vietnam tours. With its quiet waters and striking scenery, Halong Bay is a peaceful yet powerful destination within any well-curated Ha Long Bay Vietnam tour.
