Turtle Island Park consists of a number of uninhabited islands lying in the Sulu Sea, off the east coast of Sabah. Turtle Island, or Selingan Island, is the largest of these islands and has been developed to house the park's headquarters, a visitors' centre, basic tourist facilities and a turtle hatchery.

The other islands are usually off limits to the casual visitor in order to keep the turtles' natural habitat pristine.

Turtle landings usually occur after dusk. The park has a sensible policy of allowing visitors to see only one landing a night. This allows undisturbed nestings to go on throughout the night. Whilst waiting for the evening's highlight, all that is left to do is to laze on the beach at sunset or snorkel. The west side of the island is ideal for this. It's clean, quiet, and offers some interesting coral and sea life. Wander around the island and you'll be surprised at how many turtles would have landed in the last few days; their tracks, like mini-tractors, remain in the sand for days.

The nearest mainland town to the park is Sandakan. Your tour operator will organise a speedboat pick-up service to and from Turtle Island. It takes about two hours to reach the islands by boat.
