Quick Facts About Ha Long Bay

Why Visit Ha Long Bay?

Ha Long Bay is internationally famous because of its dramatic seascape of thousands of limestone islands and islets rising from calm green water. It is one of the most recognisable destinations in Vietnam and a classic choice for travellers who want a scenic cruise, cave visits and iconic views. However, the wider Ha Long Bay region is not only about large cruise boats. By travelling through Cat Ba Island and Lan Ha Bay, visitors can enjoy the same limestone scenery with a more active and local adventure focus.

Ha Long Bay, Lan Ha Bay and Cat Ba Island

Many travellers use the name Ha Long Bay for the whole limestone bay region, but there are several areas with different travel styles. Ha Long Bay is the most famous and busiest area, Lan Ha Bay is quieter and better for kayaking, and Cat Ba Island is the main base for trekking, cycling, local villages and multi-day adventure tours.
