Bartlesville's "Favorite Festival and Event" as voted by the community! Join us for a long weekend as we kick off the summer. Visit Bartlesville and our premier arts & entertainment festival at Sooner Park, located at Madison Boulevard and Tuxedo Avenue in Bartlesville, Oklahoma. A delightful variety of regional and local artists and entertainers will return to Sunfest at the beginning of every summer. Jazz, rhythm and blues, rock, bluegrass, contemporary Christian, and original music variations will fill Sooner Park with sound for three fun-filled days. Dozens of groups and individual acts provide free entertainment on stage and other spaces throughout the park.
