Serpentine National Park is a protected area in the Darling Range of southwestern Western Australia located inland from the Perth metropolitan area. The park preserves riverine and jarrah‑forest habitats along the Serpentine River corridor.

The park’s primary attraction is Serpentine Falls, which includes a developed lookout, picnic facilities and short walking trails that connect the car park to viewing points. Visitors use the site for short walks, picnics and photography rather than extended backcountry hiking.

The area around the Serpentine River has been managed for water supply and recreation; the park safeguards key riparian vegetation and public access to the falls. Facilities are concentrated near the main car park and lookout to limit impact on surrounding bushland.

The park lies within the Shire of Serpentine‑Jarrahdale in southwestern Western Australia and is accessed by regional roads from the Perth area.

  • Best time to visit: The falls are most impressive after winter and spring rains; walking trails and a lookout provide the main visitor access points.

What to See #

  • Serpentine Falls: A waterfall with an established lookout and short walking trails that provide access to viewing platforms and picnic areas.
