Similajau is Sarawak's long, thin coastal park — a ribbon of rainforest, golden-sand beaches and rocky headlands stretching along the South China Sea just northeast of Bintulu. Gazetted in 1978, it is best known for the aptly named Golden Beach and Turtle Beach, reached by a coastal trail that threads between forest and shore for kilometres.
The park's wildlife runs from gibbons and long-tailed macaques in the canopy to marine turtles that come ashore to nest, and estuarine crocodiles inhabit its river mouths — heed the signboards and keep to the marked trails and beaches.
