Phi Phi Islands : How Beautiful Is This World-Class Diving Destination?

The Phi Phi Islands in Krabi are one of the most precious gems of the Andaman Sea and are consistently ranked among the best diving destinations in Thailand and Southeast Asia. Their towering limestone cliffs, crystal-clear turquoise waters, and rich underwater ecosystems make Phi Phi a dream destination for divers around the world.

The true charm of Phi Phi is not only above the water—its underwater world is filled with colors, depth, and life that few places in the region can compare to.

1. Remarkable Water Clarity with 20–30 Meters of Visibility

One of the main reasons Phi Phi is globally recognized is its exceptional underwater visibility.

From November to April, the sea becomes remarkably calm and clear, with almost no sediment.

Divers can clearly see:

all in sharp detail, even at significant depths.

With its limestone structures, the coral formations grow along vertical walls and deep underwater ridges, creating dynamic, multi-layered coral landscapes rarely found in flat reef systems.

Many areas—especially Bida Nok, Bida Nai, and Loh Samah Bay—are considered some of the healthiest coral zones in Thailand.
