Kusu Island is one of the Southern Islands in Singapore, located about 5.6 kilometres to the south of the main island of Singapore and below the Singapore Straits. "Kusu" means "Tortoise Island" or "Turtle Island" in Hokkien; the island is also known as Peak Island or Pulau Tembakul in Malay.
It can be taken by a boat from Marina South Pier. From two outcrops on a reef, the island was enlarged and transformed into an island of 85,000 square metres.
