The Great Prosser Balloon Rally
September 25–27, 2026
Experience the wonder of colorful balloons, breathtaking views, and family-friendly fun in Prosser.
A tradition worth waking up for
Before the sun rises over the valley, pilots study the wind, crews prepare for flight, and spectators gather in anticipation of the day ahead.
Since 1991, the Great Prosser Balloon Rally has brought pilots, volunteers, neighbors, and visitors together to celebrate the beauty of flight. Every morning offers something different, but the sense of community and wonder remains the same. Whether balloons fill the sky or weather keeps them grounded, there’s always magic to be found on the field.
Sunrise Launches
Arrive before sunrise and watch the magic unfold as pilots and crews prepare for flight and colorful balloons slowly take shape against the morning sky. Meet fellow spectators, enjoy the energy of the field, and be part of one of Prosser’s most cherished traditions.
When conditions are safe, balloons lift off around sunrise and drift wherever the wind leads. Because safety is our top priority, balloon activity may be limited to inflation only or canceled altogether due to weather conditions.
Night Glow
Make plans to join us at the Prosser Airport on Saturday evening for Night Glow. Bring a lawn chair or blanket, enjoy a picnic or dinner from one of our food and beverage vendors, and settle in for a fun-filled evening with family, friends, and the GPBR community. Please note that alcoholic beverages are not permitted on airport grounds.
Enjoy live entertainment by the Bram Brata Steel Drum Band from 6:00 to 7:00 p.m., then experience Night Glow, a favorite family tradition, as colorful balloons illuminate the field and dance to music shortly after sunset, weather and wind conditions permitting.
Free Ben Franklin Transit shuttle service will be available for Night Glow from 5:30 to 8:30 p.m.
A little planning goes a long way
A few simple tips can help you make the most of your Rally experience, whether you’re joining us for sunrise launches, Night Glow, or the entire weekend.
Arrive early
Give yourself plenty of time to park, find a viewing spot, and watch pilots and crews prepare for flight.
Dress in layers
Early mornings can be cool, even during warm weather. Dressing in layers allows you to stay comfortable as temperatures change throughout the morning.
Check the weather
All balloon activities are weather dependent. Launch and Night Glow decisions are made onsite based on current conditions and safety requirements.
