The Visitor Center is open seven days a week from 8 a.m. to 5 p.m., and contains exhibits about the battle, a twenty-nine minute film, an eight-minute fiber optics map program and a bookstore. An excellent Civil War research library is open to visitors from Tuesday through Saturday. The Wilson's Creek Civil War Museum (formerly the General Sweeny Museum), an outstanding collection of original Civil War artifacts relating to the war west of the Mississippi River, is located just north of the battlefield Visitor Center.  The museum is closed December, January, February and March. The park entrance fee includes admission to the Civil War Museum.

All park facilities are closed Thanksgiving Day, Christmas Eve, Christmas Day and New Year's Day.

In addition to the Visitor Center and Civil War Museum, the Ray House is open periodically through the summer, with interpreters dressed in period clothing giving guided tours.
