About the Community

Located about 10 miles east of Sunnyside, the town of roughly 6,000 residents offers you a picturesque perspective of rural America at its best.

The Yakima River meanders through town past several grassy parks, where picnicking, cycling, walking and jogging are favorite activities for locals and visitors.

Tales of the past can be found nearly everywhere. Check out the interesting old headstones in the cemetery. Tour historic downtown, the Benton County Courthouse, the Benton County Historical Museum, and the many Victorian style homes that quietly grace the city.

Prosser is surrounded by vineyards and orchards that produce some of the finest fruits, vegetables and wine grapes in the world. Local harvests have inspired gourmet dried cherries, fancy pickled vegetables, wreaths of culinary herbs, and English walnut treats.

The Washington State University Irrigated Agriculture Research and Extension Center is the largest of its kind in the world. It is known globally for its research concerning numerous irrigated crops. Visitors and scientists from over 50 countries tour the facility every year.

The city’s big event is the Great Prosser Balloon Rally in September. That weekend also features the Harvest Festival and Street Painting Festival.
