This dive site, Koh Kai, also known as Chicken Island, is an excellent entry point for new divers and snorkelers due to its gentle underwater topography. Featuring gently sloping reefs, navigation is straightforward, allowing divers to easily explore the diverse coral formations. While specific historical details are not provided, its name likely originates from the distinctive chicken-head-shaped rock formation visible above the waterline, making it a picturesque and easily identifiable location.
The vibrant underwater environment is home to healthy hard and soft corals, providing a rich habitat for various marine species. Divers can expect to encounter an array of colorful reef fish, including popular species like clownfish and parrotfish. Other common residents include moray eels and pufferfish. With a bit of luck, divers may also spot stingrays gracefully gliding across the seabed and sea turtles navigating the reef.
Generally offering good visibility and mild currents, Koh Kai is suitable for diving year-round, although the best conditions often align with Thailand's dry season. Its shallow average depth of 6 meters and maximum depth of 12 meters make it ideal for extended bottom times and relaxed exploration. For freedivers, the calm conditions and accessible depths provide a perfect setting for practicing breath-hold diving. It's a highlight for those seeking a tranquil and colorful reef experience in the Krabi region.
