Plan the visit
Use the second-full-weekend rule as the planning window
Sweetwater's city visitor page states that the roundup is held on the second full weekend in March, while the Nolan County Coliseum describes it as an annual second-weekend event. Texas Defined maps that recurrence to March 12-14, 2027 while leaving year-specific hours, tickets and program details to the future organizer schedule.
Expect several related events rather than one attraction
The city and local host sources describe a broader weekend that can include the roundup, parade, carnival, demonstrations and other community activities. Check the final 2027 program before travel so you know which pieces are at the coliseum and which occur elsewhere in Sweetwater.
Build in Sweetwater and Nolan County
The roundup can anchor a wider West Texas weekend. Leave room for Sweetwater's railroad and aviation history, local museums and other Nolan County stops instead of treating the visit as only a few hours at the coliseum.
