Ellis Brook Valley Reserve, Nature reserve in City of Gosnells, Australia.

Ellis Brook Valley Reserve is a nature reserve with four distinct walking trails spanning over two kilometers through wetlands and woodlands home to many native species. The paths connect different habitats and provide opportunities to observe the variety of plants and animals that live here.

Ellis Brook Valley Reserve was gazetted in 1986 to protect bushland on the lower slopes of the Darling Scarp within the City of Gosnells. The reserve lies in the catchment of Ellis Brook, which drains the scarp into the Swan coastal plain. Its later management has focused on controlling weeds and dieback and on replanting local species along the brook.

The reserve lies within the traditional country of the Whadjuk Noongar people, whose name for the Canning River is Djarlgarra. The valley's granite outcrops, wetlands and jarrah-marri woodland provided food, water and shelter, and Noongar knowledge of these plants and seasons is still passed on today.

Two car parks serve the reserve: Honeyeater Hollow off Rushton Road and Valley Head at the end of the access road. The main trail climbs about 60 metres past Sixty Foot Falls to the granite outcrop; the descent is steep and slippery after rain. Wear closed shoes and carry water, as there is no drinking water on site.

The area is home to over 500 wildflower species and features a seasonal waterfall, Sixty Foot Falls, that flows after heavy winter rainfall. This rare cascade forms only during wetter periods and reveals how seasonal rain patterns shape the landscape.
