These four specks of land known as Talang-Satang National Park in the South China Sea are home to a turtle hatchery with a programme to release hatchlings back to sea. Overnight visitor numbers are limited and accommodation is basic, but the rewards are high. During the day, relax, read or swim in the clear waters. At dusk, turtles will start landing on the beach to lay their cache of eggs. Rangers lead tourists to watch the laborious task and then to the hatchery to release young turtles. This is a great destination for adventurous travellers as turtles arrive on many nights of the year. Several operators do arrange tours to the island.
