What to do?
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.
The dam is a part of Serpentine National Park, therefore entry fees apply.
