Ao Ton Sai (Ton Sai Bay)

Ao Ton Sai is the bay that defines Phi Phi Don's character. The curved shoreline serves as the island's harbor, with longtail boats bobbing in turquoise water against a backdrop of towering limestone cliffs. The beach itself is functional rather than postcard-perfect — this is where boats launch and passengers wade ashore. But the setting is stunning, and watching the waterfront activity from a nearby restaurant is a classic Phi Phi moment.
