Separated from the mainland of Phuket by the Khlong Tha Chin, a shallow mangrove swamp, this twenty square kilometer island is connected by a causeway to the city. Wat Ko Sire, on the hill, has a large Reclining Buddha and provides fine views of the surroundings. Phuket's largest settlement of Sea Gypsies, or Chao Ley, are on Ko Sire at Leam Tuk-kae. Swimming is not present because of the muddy bottom. There are some popular seafood restaurants on the eastern shore.
