ToggleWhere Is Lan Ha Bay?
Lan Ha Bay lies just south of the iconic Halong Bay and to the east of Cat Ba Island, in northern Vietnam’s Hai Phong Province. This tranquil bay is part of the Gulf of Tonkin and is about 150 kilometers from Hanoi, taking roughly 2.5 to 3 hours by road and ferry.
While Halong Bay draws global attention as a UNESCO World Heritage Site, Lan Ha Bay remains a lesser-known gem. It features the same dramatic limestone karsts, emerald waters, and hidden caves—but with fewer tourists, less boat traffic, and more untouched charm. It’s the perfect alternative for travelers seeking serenity, authenticity, and eco-friendly adventures in Vietnam.

Lan Ha Bay vs. Halong Bay: What’s the Difference?
While Lan Ha Bay and Halong Bay are neighboring destinations that share the same spectacular seascape of towering limestone karsts, calm emerald waters, and hidden caves, they offer distinct experiences for visitors.
Halong Bay, a UNESCO World Heritage Site, is widely recognized as one of the world’s most iconic natural wonders. Its fame, however, has made it a bustling tourist hub, with hundreds of boats and a well-developed infrastructure catering to large volumes of visitors.
By contrast, Lan Ha Bay, located just to the south of Halong and extending around the eastern edge of Cat Ba Island, remains relatively untouched. Often referred to as Halong Bay’s quieter sister, Lan Ha Bay boasts the same dramatic geological formations but sees far fewer tourists, offering a more peaceful and intimate atmosphere.
In addition, Lan Ha Bay features over 100 small beaches, many tucked between limestone islands, which are perfect for swimming, snorkeling, and kayaking. Halong Bay, though visually similar, offers fewer accessible beaches and more structured excursions.
Lan Ha Bay is also known for its traditional floating fishing villages, such as Cai Beo, where visitors can gain insight into the lives of local fishermen. While Halong Bay has similar communities, they are often more commercialized and integrated into standard cruise itineraries.
For travelers seeking a quieter, more authentic, and more nature-oriented experience, Lan Ha Bay is an ideal alternative to the more famous—and more crowded—Halong Bay.
