Little Rock Central High School National Park is famous for its contribution to the Civil Rights Movement. In 1957, nine African-American students were barred from entering the school even though the Supreme Court had ordered public school integration several years earlier. These nine students faced a group of protesters trying to deny them access to the school. President Eisenhower called on the Army's 101st Airborne to escort the children into the school and to protect the students' rights throughout the remainder of the school year.

Pea Ridge commemorates the famous Battle of Pea Ridge. In March 1862, this Civil War battle played a decisive role in ensuring Missouri did not fall under Confederate control. Pea Ridge has over 7 miles of trails for hiking and outdoor enthusiasts.
