Condé Nast Traveler recently named the Phi Phi Islands one of the "25 Best Places to Go Snorkelling in the World."
In the Phi Phi Islands you can snorkel in clear blue-green water, surrounded by towering cliffs. There's no question as to why it was chosen as one of the best places in the world to snorkel. Have you snorkelled in the Phi Phi Islands?
Hire a long-tail boat from Tonsai Pier on Koh Phi Phi Don and high-tail it to Pi Leh Bay on Koh Phi Phi Leh. Here, you'll snorkel in incredibly clear, green water surrounded on both sides by 330-foot-tall limestone cliffs (note that the sun only hits the water between 11 a.m. and 1 p.m., so plan accordingly for the best photo ops).
