The Ravalli County Fair, in beautiful Hamilton MT is the largest event in the Bitterroot Valley each year. Typically the last weekend in August, we bring in 20,000 people through our gates. Low gate admission, free parking, and loads of free entertainment. Free admission to all Arena events, lots of seating in the historic grandstand. New speaker system in 2014! This is a family friendly, rural county fair... just like they ought to be! We will see you at Fair!
