Halong Bay, Vietnam: Top 10 Must-Do Activities

Classified as a UNESCO World Heritage Site, Halong Bay is one of the most celebrated natural gems in the world.

Located in northern Vietnam, this geological marvel hosts nearly 2,000 limestone islands and islets that rise from an emerald-colored sea, forming a breathtaking landscape.

Often described as a “living sculpture,” Halong Bay fascinates as much for its beauty as for its legends.

But how can you make the most of this exceptional site?

Here is the Top 10 of activities to do in Halong Bay to live an unforgettable experience with Horizon Vietnam Travel.
