A guide to Thaa Atoll.
Thaa Atoll is a quiet, undeveloped atoll offering genuine remoteness and exceptional marine biodiversity. The atoll features pristine dive sites with healthy coral formations, regular manta ray sightings, and uncrowded beaches. A small number of resorts provide luxurious seclusion for those willing to venture further south.
Historically known as Kolhumadulu, Thaa is ranked among the 21 largest atolls in the world. The island of Kinbidhoo contains the ruins of a large Buddhist stupa, documented by Maldivian historian Muhammad Ismail Didi, a reminder that the archipelago was Buddhist for more than a thousand years before converting to Islam in 1153 AD.
