Further south, the Cat Ba Archipelago contributes its own limestone islands to the wider seascape, with Cat Ba Island itself standing out as the largest landmass in the system at about 200 km² (77 sq mi).Cat Ba Island area Between Ha Long Bay, Bai Tu Long Bay to the north-east and Cat Ba to the south, the region presents a continuous belt of limestone pillars and sheltered channels.
