This dive site, Koh Bida Nai, is a small rocky island south of Phi Phi Lee, forming part of the renowned Phi Phi Islands dive destinations in Thailand. It features dramatic limestone cliffs that extend underwater, creating an engaging topography for exploration. Divers typically navigate around the island, exploring its vibrant reefs and seeking out marine life along the wall and slopes. There is no specific historical narrative associated with the site, but its natural beauty is a testament to the region's geological processes.
The waters around Koh Bida Nai teem with a wide array of marine life. Divers can expect to encounter an abundance of small fishes and diverse shellfishes, making it an excellent spot for macro photography and observing intricate reef ecosystems. Lucky divers might also witness the majestic presence of blacktip reef sharks patrolling the shallower areas, and graceful sea turtles gliding through the water, adding an exciting element to the dive experience. The limestone structures are adorned with various coral formations, supporting this rich biodiversity.
The best time to visit Koh Bida Nai, like much of the Andaman Sea, is generally during the dry season from November to April, when visibility is often at its peak. Highlights include the dramatic underwater landscapes formed by the limestone cliffs and the potential encounters with larger pelagic species. The site's diverse depths, ranging from 5 to 18 meters (and sometimes deeper in nearby areas), make it suitable for both beginner and intermediate divers, as well as freedivers and snorkelers who can enjoy the vibrant shallow reefs. Always be mindful of potential boat traffic and follow local dive operator guidelines for a safe and enjoyable dive.
