Exploring the underwater world at Koh Haa is a thrilling adventure not to be missed by diving and snorkeling enthusiasts. It is a group of 5 small islands, about 45 min Southwest of Saladan. Koh Haa Yai, the biggest of the 5 islands of Koh Haa, hosts one of the most famous diving spots in the South Andaman, namely the Cathedral. On its southeast side you will find 2 huge underwater Caverns, starting at a depth of 9m with the bottom at about 14m. (entry only for certified divers). They are connected via a swim through, and those who want can surface inside the Cathedral and take a breath without regulator to have a look at the stalactites formed over the years. These hidden gems offer a glimpse into an enchanting world beneath the waves. Further out, this mesmerizing location is adorned with an array of vibrant soft corals, graceful sea fans, and majestic hard corals, creating a breathtaking spectacle for all who venture below the surface. Not to mention an amazing variety in macro life, all the general reef fish, and of course the occasional bigger pelagics. Islands 2, 3 and 4 host a shallow lagoon (5-6m) with turquoise waters and a stunning beach, perfect for both snorkelers and beginner divers taking their first breath beneath the surface. On the most northern island nr 1 we find another famous dive spot, named the Chimney, which is a tunnel starting at a depth of 5m and ending at a depth of 18m (only for Advanced divers with perfect buoyancy control). The tunnel system is connected to another smaller cave called the fish bowl.
