There’s a reason why this magical seascape in the Gulf of Tonkin, northeastern Vietnam, is a UNESCO World Natural Heritage site and one of the New 7 Wonders of Nature. Virtually untouched, there are over 1,600 islets that dot the bay like jewels.

This unique and diverse karst landscape (land comprised of sandstone) is popular for an array of activities, from boating, swimming and kayaking, to exploring the Halong Bay caves. These geologically fascinating caves are the result of years of coastal erosion, and a must-see!

  2. Also a good idea to travel to Catba Island and from there visit the less explored part of Halong Bay. Less crowded and as beautiful as HB 🙂

    • Yes, Lan Ha Bay is less crowed. However, now there are a lot of nice cruises starting from Got Pier in Hai Phong to Lan Ha Bay. So starting from Cat Ba Island is not only one option for Lan Ha Bay like the past. I hope you will come back to Vietnam and have a chance to try that. You may check Incredible Asia Journeys Site for different cruises in Lan Ha Bay and you will see it. Some good option cruises like VSpirit Premier, Escape Sails.
