This dive site, Mango Bay Ko Tao, is renowned as an excellent location for dive training due to its diverse underwater topography. It features a large sandy area that gently slopes from 1 meter down to 16 meters, providing ample space for skill practice and buoyancy training. Additionally, two distinct areas of large artificial reef concrete cubes offer unique structures for advanced buoyancy or technical diving exercises. The east side of the bay boasts a dense hard coral reef, while the west side is characterized by a rocky sloping reef.
The marine life here is abundant, featuring a variety of small coral reef fish species, including triggerfish, catfish, gobies, porcupine pufferfish, parrotfish, wrasse, and anemone fish. Turtles are frequent visitors to the area, often seen gracefully swimming amidst the corals. Rays are also occasionally spotted, adding to the site's biodiversity. The hard coral formations themselves are a significant highlight, creating vibrant underwater gardens.
The best time to visit Mango Bay Ko Tao for diving or freediving is generally during the dry seasons, typically from February to April and May to September, when visibility is usually excellent and sea conditions are calm. Its shallow depths and protected nature make it ideal for beginners and those looking to refine their skills in a relaxed environment. Freedivers will appreciate the clear waters and varied depths for practice, while snorkelers can enjoy the vibrant coral reefs and marine life close to the surface.
