Duncan Farmers Market | The Duncan Farmers’ Market is located in historic downtown Duncan in the beautiful Cowichan Valley on Vancouver Island. Every Saturday, year round, you will find a sea of tents in the market square on Craig Street and down Ingram Street under which more than 100 vendors sell their wares.  As a true farmers’ market, we give priority to farmers and growers, and we also play host to an amazing array of local artisans and makers offering the unique and unusual.
