Koh Bida Nok & Koh Bida Nai are two islets off the southern tip of Phi Phi Leh in the Andaman Sea, part of the Phi Phi Islands in Thailand. These rocky outcrops are renowned for their stunning underwater scenery, making them popular spots for diving and snorkeling. The waters around the Bida Islands teem with a wide array of marine life, including colorful coral formations, numerous species of fish, sea turtles, and even the occasional reef shark. The visibility is often excellent, providing a clear view of the underwater spectacle. Above water, the islands are characterized by sheer limestone cliffs and small beaches that emerge during low tide. Due to their natural beauty and rich marine biodiversity, the Bida Islands are protected under Thai national park regulations. Visitors typically access these islets by boat on day trips from Koh Phi Phi Don, which is the only inhabited island in the Phi Phi archipelago. Activities here extend beyond diving and snorkeling to include rock climbing and photography, as the islands offer exquisite backdrops for adventure enthusiasts.
