Occupying a remote, rugged peninsula at Sarawak’s far northwestern tip, this 14-sq-km national park features endangered mixed dipterocarp rainforest, jungle trails that hear few footfalls, crystal-clear seas, unspoilt coral reefs and near-pristine white-sand beaches on which endangered turtles occasionally lay their eggs. Few visitors make the effort and brave the expense to travel out here, but those who do often come away absolutely enchanted.
