What Is Lan Ha Bay

Administratively, Lan Ha Bay is belong to Hai Phong City, a coastal city located about 119.8km from Hanoi Capital, Vietnam. The entire bay has an area of 7000 m2 wide in the southeast of the Cat Ba Archipelago. Lan Ha Bay comprises around 300 karst islands, with the bay’s pristine waters coloring a lush emerald in between. The scenery is magnificent enough that it’s been featured many times in travel magazines worldwide.

The meaning of the name: “Lan Ha” in English mean a elegant orchid  from Heaven come down to Earth to beautify the area.

What to expect? 


Unlike its more popular counterpart, Halong Bay, this hidden treasure remains relatively undiscovered by mass tourism. So, tourists who have done their research and knowledge of the place will have a much more immersive experience when visiting the site.

Other than the karst islands, visitors also have the opportunity to visit the small, secluded beaches in the area. While they’re not large, they’re private enough that you’ll have a much better time sunbathing or immersing yourself in the crystal-clear water of the archipelago.
