The Sisters Rodeo Grounds, southeast of town off Highway 20, host the annual Sisters Rodeo — a four-day PRCA professional rodeo in early June with all the standard events: bull riding, bareback bronc, saddle bronc, team roping, barrel racing, steer wrestling. It has been running since 1940 and is one of the longer-established rodeos in the Pacific Northwest. Tickets sell out and accommodation books up months in advance.
Outside of rodeo week the grounds host occasional smaller events — youth rodeos, fairs, the Stage Stop event in autumn. The site itself is just a permanent arena with bleacher seating, and there is no reason to visit when nothing is on. Check the event calendar before planning a stop.
