Prosser

Part of the Yakima Valley's fruit growing district, Prosser is the county seat of Benton County, and home to the Benton County Historical Museum.

The treeless Horse Heaven Hills, where wild horses once roamed, rise to the south and Horse Heaven Vista offers a panoramic view of the lower Yakima Valley, the Cascades and the Yakima River.

Prosser is part of the Richland-Kennewick-Pasco, WA metro area.
