Thaimuang beach is approximately 13.6 km. long sandy beach with white sand, clean and calm area. It is an important place for sea turtle spawning such as Leather back turtle, Green turtle and Olive ridley turtle. The mostly found is Leatherback turtle.
During November to March each year, park staff will survey the sea turtle every night to prevent turtle eggs stealing from resident in the area. If they find turtle lay up, they will move turtle eggs to hatch in a safe place and then released into the sea.
