The Swan Valley, with fertile soil, uncommon in the Perth region, features numerous wineries, such as the large complex at Houghtons, the state's biggest producer, Sandalfords and many smaller operators, including microbreweries and rum distilleries. The Swan Valley also contains specialised food producers, many restaurants and cafes, and roadside local-produce stalls that sell seasonal fruit throughout the year. Tourist Drive 203 is a circular route in the Swan Valley, passing by many attractions on West Swan Road and Great Northern Highway.
