The 37th annual Great Prosser Balloon Rally will take to the skies September 25-27, 2026, at the Prosser Airport. Early morning launches fill the sky with color as sunrise comes over the Horse Heaven Hills and the Yakima River. Join the balloons on the field to watch the pilots and crews inflate the balloons, then follow along on their flight to wherever the wind takes them. All launches are weather permitting!
