Nui Bay

A tiny cove with white sand and clear water on the west coast, enclosed by limestone cliffs. Most visitors arrive by longtail or kayak; the walking approach from Loh Bagao crosses the ridge and the final stretch along the shore is only passable at low tide. Snorkelling off the rocks is good and there are no facilities, so bring water.

Nui Bay is at Nui Bay on the west coast of Phi Phi Don, reached by longtail from Tonsai or by the jungle trail from the viewpoint.

Not that we know of. This page on kohphiphi-live.com shows what Nui Bay is and where to find it.
