The Avon River drains the Great Southern and Upper Great Southern regions, actually starting as a river near Wickepin. The Avon River is 295 kilometres in length and the basin covers an area of 120,000 square kilometres, extending from Northam in the west to Southern Cross in the east, north to Dalwallinu and south to Pingrup. From its confluence with Wooroloo Brook in Walyunga National Park the Avon becomes the Swan River. Approximately 60% of the Swan River’s flow is from the Avon River.
The main Northam Pool on the Avon River (start point for the Avon Descent) is the only permanent stretch of natural inland water along the entire Great Eastern Highway between Perth and Adelaide.
The Avon Descent passes through some of Western Australia’s most picturesque country. You will travel through the farming regions of historic Northam and Toodyay, forested national parks, steep gorges, the Swan Valley vineyard region and, eventually, into the tidal waters of the upper Swan River.
The Avon Descent offers competitors conditions ranging from long stretches of flat water that can test the endurance of the fittest athlete through to rapids, sure to test the skills of all who attempt to navigate their unknown contours.
