Ko Si and Ko Ha
in Songkhla Lake, can be reached by leaving from Tambon Lam Pam pier (25 kilometres) or Pak Phayun pier (10 kilometres). The travelling time is
about 1 hour. The islands are home of flocks of sea swallows, so many
that they are called Ko Rang Nok (birdís nest island).
Concessions are given out for the collection of the nests for sale. The
natural beauty of the islands is one of the finest in Phatthalung. King
Rama V once visited here and left his initials on a cliff. Nearby is a
monument of him. As Ko Si and Ko Ha are concession areas of the private
sector, permission must first be obtained in Pak Phayun district.
