Fairs and festivals abound on Long Island during the summer months, and that’s great news for families. These outdoor celebrations offer perfect opportunities for old-fashioned family fun.
Some of our picks are annual events, while others are just getting started, and some transform our favorite main streets into no-car zones. You'll even find some cool extras, like live music. Find more ways to celebrate the season in our Ultimate Long Island Kids Summer Vacation Guide, which includes our story on Long Island's best fireworks displays.
As always, click through our listings for full details, including recommended ages, costs, and times.
