Spratly Islands, the municipality is the
westernmost point in the Philippines. It is separated from
Sabah by the
Balabac Strait. The municipality consists of some 36 islands, including the eponymous
Balabac Island. The islands are notable for their uncommon
indigenous plant and animal species, such as the nocturnal
Philippine mouse-deer (or Pilandok). The islands are also home to
dugongs,
saltwater crocodiles,
sawfishes, and

UNESCO World Heritage Site nomination in the future. The Balabac Great Reef located in the town of Balabac is geographically the
westernmost point of the Philippines.
