Nui Bay beach on Phi Phi island is a stunning secluded paradise with crystal clear waters and spectacular surroundings. Located at the northern tip of Koh Phi Phi Don, it's only accessible by foot or longtail boat – making it a great escape away from busy tourist spots. Once there, you'll find an idyllic stretch of white sand embraced by lush jungle-covered cliffs – perfect for soaking up some sun and taking in the mesmerizing views. The beach has excellent snorkeling opportunities, with plenty of rock formations and colorful aquatic life to explore – plus there are even some small caves tucked away if you look hard enough!
