Thailand’s Phi Phi Islands – Limestone Cliffs & Bioluminescent Tide "A breathtaking tropical night along the Phi Phi Islands in Thailand, where towering limestone cliffs rise from the darkened sea. The water glows with neon-blue bioluminescence as gentle waves roll onto the sand. Fireflies dance among the jungle trees, and a crescent moon hangs above, casting a soft golden glow over the tranquil scenery."
