With magnificent coral just below the surface and a vast number of colored fish reflecting the sunlight, one only needs to float on top of the water with a mask and snorkel to enjoy Phi Phi Islands' stunning beauty. Just south of Thailand's Phuket, this small group of islands has firmly established itself as one of the world's foremost snorkeling holiday spots.

"To the uninitiated, Phi Phi's snorkeling is like being on a fantasy planet. Even the experienced agree - it's good. Really good. With one of the world's most abundant coral reef systems, the locations and sights are both plentiful and astounding (Phiphi.phuket.com)."
