Marietta Riverfront Roar
Summer in Marietta begins and ends on the water. During the second full week in July, powerboats roar into town for the Riverfront Roar and a weekend of professional tunnel boat racing. Admission is free and visitors can view the boats up close, meet the drivers, and cheer on their favorite racing team from the levee. Cool down at the beer garden and visit downtown shops and vendors. Fireworks and live music conclude the racing on Saturday.
