There’s nothing like knowing exactly where your food came from. Sure, a vast produce selection at Shaw’s is convenient and easy, but supporting local farmers, gardens and growers is a sustainable option for feel-good foodies. With so many resources in the area, that calls for a reason to celebrate.

And today, local enthusiasts and resources have come together to do just that. The 4th annual Boston Local Food Festival will honor the nearby New England farmers and vendors, as well as welcome the fall harvest season, by putting together the largest one-day farmers market from 11 a.m. to 5 p.m. on the Rose Kennedy Greenway.

If you love local, the festival is the perfect place to connect your appetite with the area’s best vendors, from farmers, to restaurants, to food trucks and organizations focused on sustainability and healthy living in New England. As part of the festivities, guests can join in on DIY demonstrations, chef talks, a seafood throwdown, crop sharing, and more. For the complete festival schedule, click here.

Of course, the weather outside isn’t the best for an afternoon spent out on the Greenway. If you’re looking for more ways to buy local during this harvest season, here are seven farmers markets open until the end of October.

They’re worth checking out—after all, Massachusetts was ranked the seventh best state for farmers markets in the United States this year. To discover more markets in the area, there’s an app that locates them for you.
