Converging all 3 national and international titles including World Biosphere Reserve, National Marine Park, National Special Scenic Site, Lan Ha Bay has a long geologic history of about 18,000 years now, bearing the global significance of tower karst (fengling) and peak - cluster depression (fengcong). This site represents the karst evolution in the final stage of a great process from high mountains to the sea where karst terrains reach the base level. Lan Ha Bay looks like a blue pearl at sea, comprising about 300 islands and islets with abundant vegetation, a hidden underground world, many beautiful and unspoiled golden sand beaches which has outlined a calm, tranquil nature picture for it.

Lan Ha Bay contains typical and significant ecosystems including (1) cave, (2) tidal flat, (3) coral reef, (4) soft bottom, and (5) marine lake. Especially, marine lake ecosystem has been attracting much attention of many domestic and world scientists. Several tens of marine lakes provide an excellent opportunity for them to monitor and study the relationship between physical and climatic movements and the evolution of biomes and species. Lan Ha Bay has a high concentration of limestone islands and islets in various shapes which divide the sea surface into smaller bays and lagoons. Being protected by these islands makes the waters of Lan Ha Bay always clear and peaceful.
