Harvest Festival
-
September 25 - September 27
The last full weekend in September is a busy one in Prosser, with the Great Prosser Balloon Rally and the Harvest Festival all in one weekend from September 25-27. After you enjoy the early morning balloon launch at the airport, come downtown for streets filled with unique, handcrafted, and one-of-a-kind vendors. Food vendors also offer up tasty treats, and the stage show on Friday & Saturday fills the air with music. Historic Downtown also hosts the Street Painting Festival during the event, on the downtown streets. We look forward to seeing you!
