Similajau National Park showcases the unique geographical features of Sarawak with a chain of golden sandy beaches, punctuated by small rocky headlands and jungle streams, and bordered by dense green forest. The park is very popular with locals at weekends. Similajau is home to 24 species of mammals, including long-tailed macaques, gibbons, banded langurs, shrews, mouse deer, barking deer, squirrels, wild boar, porcupine, and civet cats.

It is also a birdwatchers paradise, with 185 species of birds having been recorded within the parks boundaries.A good way to get the most out of Similajau is to hire a boat and be dropped off at Golden Beach and then trek back to the HQ (or vice versa). Boats can be hired for half day and full day coastal and river tours, or for crocodile spotting tours at night.
