Lan Ha Bay sits just south of Halong Bay and is officially part of the same UNESCO World Heritage-listed system, but it has a quieter, more secluded feel with over 300 limestone islands and outcrops. It is a favorite for travelers who want the same dramatic scenery with noticeably fewer boats around.
Highlights among Lan Ha Bay's attractions include Ba Trai Dao Islets, well known for a white-sand beach and clear water, and Dark and Bright Cave, best explored by kayak through its two connected caverns. Trung Trang Cave on Cat Ba Island and the quiet Ao Ech Area are popular half-day stops, while Viet Hai Village, a small fishing community, offers a look at everyday life away from the main tourist routes. Lan Ha Bay is best explored on an overnight cruise, giving enough time to combine swimming, kayaking, and a village visit into one relaxed itinerary.
