The Blaine County Fair runs August 5–8, 2027, with Bear Paw Roundup PRCA Rodeo Thursday and Friday and the Small Town Beat Down demolition derby Saturday. A Kids Rodeo listing gives a date before the fair begins.

All times are local to the venue · America/Denver
The announced grandstand program moves from two rodeo nights to a Saturday derby. The main scheduling wrinkle is the Kids Rodeo: its listed 10 a.m. date, August 1, falls before the fair’s August 5 opening, so it should not be treated as a confirmed fair-week session.
The fair homepage lists the Kids Rodeo for Sunday, August 1, at 10 a.m. That is before the fair’s announced August 5–8 run. The same homepage promotes three days of rodeo, but does not give a corrected Kids Rodeo date; confirm with the organizer before planning to attend it during fair week.
The 2027 page does not publish general fair opening or closing hours. The three timed grandstand events are listed separately below; their times should not be read as the fairgrounds’ daily hours.

The Blaine County Museum is an off-fairgrounds option for visitors extending their time in Chinook. Regional tourism information describes exhibits on Assiniboine and Gros Ventre cultures, Chief Joseph and the Nez Perce, and the Homestead Era. The museum also has a fossil room where visitors can handle fossils; these are museum offerings, not fair activities.
Sixteen miles south of Chinook, Bear Paw Battlefield commemorates the 1877 surrender of Chief Joseph and his band of Nez Perce after a journey of about 1,700 miles across what are now Washington, Idaho, Wyoming and Montana. The museum serves as the battlefield’s interim visitor center and has Nez Perce and military artifacts and an audiovisual account of the battle. Chinook’s Blaine County Wildlife Museum is another separate local museum, focused on wildlife of the area.
