Serpentine Dam

Both natural beauty and history can be appreciated at Serpentine Main Dam, which is situated amidst classic scenery in the Darling Scarp. It is the larger of the two dams located on the Serpentine River.


Please note: picnic and recreational areas at Western Australian dams managed by Water Corporation will be closed from Monday, 30 March 2020, in line with advice to cease non-essential travel. For more information visit our latest updates page.

Picnic area at Serpentine Dam

Picnic area at Serpentine Dam

Have a family lunch in the large picnic area with an adjoining playground. You are welcome to use the free gas barbecues located in the grassed lower picnic area downstream of the dam wall. 

If you prefer a relaxed indoor setting, try the restaurant near the main car park for a casual meal.

Enjoy a nature walk on the marked trails and visit the scenic lookouts. If you like bird-watching, search for kookaburras, black cockatoos, parrots, magpies, and wrens. 

Take a trip to the stunning Serpentine Falls for a picnic lunch with the waterfall as your backdrop. July to November is wildflower season, so visit during these months to see beautiful native flowers.
