An annual tradition that has been running for almost 60 years, and is a core part of Deltan history and culture. Happening every year in mid-April, the festival features music, craft sales, petting zoos, historic village tours, and a lot of food, specifically maple syrup and pancakes.
Built in 1810, the old mill has been restored to its former glory by the Delta Mill Society, a non-profit volunteer group. The mill is open to the public from the Victoria Day long weekend in May to Labour Day in September and during special Delta events (Maple Syrup Festival, Delta Harvest Festival and Celebrating the Season). In addition to its impressive architecture, it features an operating water wheel and mill stones. Heritage grain is ground into flour using the old mill stones several times during the season.
