Lan Ha Bay: A Guide The Less Touristic Alternative For Halong Bay

Lan Ha Bay is made up of around 300 karst islands and limestone sea rocks and can be found southeast of Cat Ba Island. As a geological extension of Halong Bay, Lan Ha Bay is equally as beautiful although it is less visited, less inhabited and therefore has the extra appeal of being a more peaceful place.

What does Lan Ha Bay have to offer?

This isolated paradise is an ideal beach location, with hundreds of undisturbed white sand beaches. While the beaches are fairly small, they are surrounded by towering limestone karsts that give visitors lots of privacy. Whilst relaxing at these tiny beaches visitors may see many butterflies and birds enjoying the many flowers and trees that sit around the edges of the sand. Lan Ha Bay is also a great place to take part in water-based activities such as snorkeling, kayaking or scuba-diving!

One unexpected activity that is possible in Lan Ha Bay is rock climbing! Some cruise operators offer the option to climb some of the ancient limestone karsts that are dotted around the bay, giving visitors the chance to see Lan Ha Bay from a very different perspective. Though it can be physically challenging, it is also extremely satisfying to climb your way to the top.

Many visitors use Lan Ha Bay as a base for visiting the nearby fishing villages and floating villages that are an integral part of Halong culture. Viet Hai Fishing Village is one of Lan Ha Bay’s top attractions where locals invite tourists to come and witness their traditional way of living. Visitors may be surprised to see that people who live on floating villages have guard dogs and even restaurants and a kind of Town Hall.
