Haad Khuad or Bottle beach is a half-circle beach on the north of Koh Pha Ngan. Named Bottle Beach for its protected cove, and known for quiet isolation on an island known mostly for its riotous Full Moon Party.

The beach is most easily reached by a long-tail boat from the northern end of the island, though this is not possible in bad weather. There is also a poorly marked mountain trail leading to the beach and primitive road which the owners of the beach's guest houses will drive you down if the boats are not running. Good viewpoint is 30 minutes by trekking to the top, you will find Koh Tao and the wide blue ocean
