Great Summer Fairs and Festivals for Long Island Families

Nothing says summer more than spending time as a family at a fair or festival on Long Island. It's a chance to be outdoors, spend time with the friends and neighbors, and make lasting memories.

Whether your family enjoys an old-fashioned street fair in your neighborhood or ventures nearby to see how other communities celebrate summer, these family-friendly events are sure to leave everyone smiling. Plus, many of these events are FREE to the public. That's why we've rounded up a list of the best fairs and festivals taking place in Nassau and Suffolk counties and on the East End in July and August.
