3rd Saturday in March Held annually as part of the Founder's Day Celebration, Bulls on the Beach is a bull riding event like you've never seen before! Bull riding and mutton bustin' return to the Granbury City Beach. It's a unique setting, to say the least. Not only is the City Beach arena different, but it's also the most popular bull riding location for Chute 2 Productions. Granbury Bull Riding on the Beach is a World Senior Pro Bull Riding Association-sanctioned event.
