Organized this year by Mary Ellen Ellwood and Patrick Mulcahy, the fair was dubbed "the largest block party around," by planners.
"The fair is a great time for people of all ages," Ellwood said. "There is something for everyone. Lots of great food and drinks, and fabulous entertainment."
Riverhead Townscape is the parent organization of the fair and all proceeds go to beautification projects around town.
This year, the fair featured over 400 craft vendors, Business Expo 2013, garden tractor pulls, food, carnival rides and midway games for children.
With ties to Riverhead's rich past, agricultural, homemaking and needlecraft exhibits and competitions were held, with over 200 categories to enter.
Animal rescue and civic groups were onhand, as will a first-ever traveling museum from the Riverhead Historical Society.
Live entertainment rocked the Riverhead Showmobile along the Peconic Riverfront; performances were also held in Grangebel Park. Some of the performances included: ReDancers, Acoustical Vision, Who Are Those Guys, Magic Beyond Imagination and Misspent Youth.
After the festival, fair goers agreed the event was a success.
"Wonderful as usual," said Riverhead resident Virginia Seidita.
