About Ao Nui

Ao Nui is a sheltered reef-and-wall dive on the northwest side of Koh Phi Phi Don. The site circles a rocky outcrop just outside the bay, with a reef slope, a small wall, and easy snorkeling on the shallow face. It is a comfortable boat dive for divers who want clear water, mild current, and plenty of coral and reef fish without the feel of a hard-current site.
