The Perlis State Park is located along the northwestern part of the Thai-Malaysian border, straddling the Nakawan Range, the longest continuous range of limestone hills in the country. The park is home to the Mata Ayer Forest Reserve and the Wang Mu Forest Reserve. It encompasses a total area of around 5,000 hectares. The Nakawan Range has beautiful, heavily forested slopes, sheer cliff faces, streams and extensive cave systems.

Some of the major attractions here include various caves such as Gua Kelam and Gua Wang Burma which is located within the 500 year-old Setul limestone formation.

The Perlis State Park is the only semi-deciduous forest in the country. Tree leaves fall in tandem to mark changes during the dry season.

Those intending to visit are required to obtain permission from the Perlis State Park management as well as engage the services of a ranger or a qualified guide.
