The Swan Valley is a region in the upper reaches of the Swan River between Guildford and Bells Rapids, Western Australia. It is bordered to the east by the Darling Scarp. Both Ellenbrook and Jane Brook lie within the region and discharge into the Swan River. There are 14 suburbs within the region including Herne Hill, Baskerville, Henley Brook, Caversham, Upper Swan, Brigadoon and Whiteman; It occurs in the City of Swan local government area.
The area was explored in 1827 by Captain James Stirling later to become governor of the Swan River Colony. Stirling was so impressed with the area that he wrote in his diary:
...the richness of the soil, the bright foliage of the shrubs, the majesty of the surrounding trees, the abrupt and red colour banks of the river occasionally seen, and the view of the blue mountains, from which we were not far distant, made the scenery of this spot as beautiful as anything of the kind I have ever witnessed...
When Stirling returned to establish the colony in 1829 he created three settlements: Fremantle as the port; Perth as the major commercial and political centre; and Guildford on the southern end of the Swan Valley region. Descendants of many of the early families still reside within the shire. Within the first ten years, two of Perth's oldest churches had been built there: the first was St. Mary's Church in Middle Swan, followed by All Saints Church, Henley Brook built at the site of Stirling's 1827 camp. St. Mary's was rebuilt in 1869 but All Saints still retains its original structure and is thus Perth's oldest standing church.
The Swan Valley is noted for its fertile soil, uncommon in the Perth region, and the recent expansion of tourism-based destinations. These include numerous wineries such as the huge complex at Houghtons, the state's biggest producer, and Sandalfords and also many small though excellent family-owned concerns. There are also several microbreweries and rum distilleries. The Swan Valley is served by roadside local-produce stalls which sell seasonal produce throughout the year. Grapes, melons, asparagus, stone fruits, citrus and strawberries are grown and sold in the Swan Valley.
In recent years the Swan Valley has attracted a strong food element in the form of a chocolate factory, coffee roasters, several beekeepers, a lavender farm, olive groves, a goat farm, cheese farms, dried-fruit producers and many restaurants and cafes.
During October the annual 'Spring in the Valley' weekend takes place; it is one of Australia's largest wine and food festivals.
