The Serpentine River is one of three rivers flowing into the Peel-Harvey Estuary which is twice the size of Sydney Harbour and provides a habitat to many species of fauna and flora, including black swans, ospreys, wild dolphins and blue manna crabs. Known as "Waangaamaap Bilya" by the Noongar people, it has helped feed families and sustain life throughout millennia.

This beautiful and easy half-day paddling trail is a great way to explore Mandurah's natural bushland. Features of interest along the way include the historic Coopers Mill, Old Mandurah Bridge and Pinjarra Station, as well as significant indigenous sites like the Barragup Fish Munga (Trap). The route's pretty waterside picnic spots, bars and restaurants, many with their own moorings, make ideal resting places.
