The Fort Sumter National Monument commemorates the official initiation of fire of the Civil War. April 12, 1861, the Confederates directed the first shot at the Union's Fort Sumter, located in the Charleston Harbor. Exhibits discuss the growing tensions between the North and the South and their eventual turn to civil war, as well as the physical and social history of the fort itself. Also on location is the site of the first U.S. victory over the British Navy, which occurred at Fort Moultrie in 1776.

The monument offerings differ at each fort. Fort Moultrie offers a 22–minute introductory video at the visitor center, exhibits, self–guided tours, limited ranger–led programming, and Junior Ranger activities. Fort Sumter offers 10–minute talks by park rangers aboard the ferry, exhibits, self–guided tours, and Junior Ranger activities. Reservations are required for school groups at both sites. The website offers lists of relevant state education standards, lesson plans, activities, a teacher's guide, photo galleries, and a webcam.

The Monocacy National Battlefield commemorates a Civil War battle fought 9 July, 1864, between the troops of Confederate Lieutenant General Jubal Early and Union General Lew Wallace. The Battle of Monocacy, or "The Battle that Saved D.C.," prevented Early from completing his campaign to relieve pressure from General Robert E. Lee and to capture Washington, D.C. Although the Confederates won the battle, the time lost permitted the Union to send reinforcements to the capital. The battle aside, Native Americans have been present in the area since the earliest human occupation of North America, nearly 10,000 years ago; and European explorers and traders arrived in the region in the early 1700s.

The park offers a self-guided six mile auto tour, a number of self-guided interpretive walking trails, exhibits, an introductory audio-visual presentation, guided tours, in-classroom speakers, and traveling trunks.

The Poverty Point National Monument makes accessible to the public some of the largest prehistoric earthworks within North America. The culture responsible for their creation lived in the first and second millennia BC, and the earthworks themselves date to between 1650 and 700 BC. The site includes an interpretive museum.

The monument offers exhibits, an audi-visual presentation, self-guided hiking trails, an archaeological laboratory, and picnic areas.

The Alibates Flint Quarries are located in Fritch, Texas, in the upper panhandle, and are the site of extensive mining operations by the local Indian tribes. The flint mined at Alibates is multicolored and uniquely suited for the formation of primitive tools. Today, a visitor center stands by the quarries, which are open to visitors year round.

The quarries offer exhibits and presentations in the visitor center, daily tours, field trip programs, and a traveling trunks service. The website offers historical information regarding Alibates, visitor information, and photo galleries of the park.

The Tupelo National Battlefield marks the location of the Battle of Tupelo, the second battle in northeast Mississippi designed exclusively to keep Gen. Nathan Forrest in Mississippi and away from Gen. Sherman's forces in northern Georgia. While the battle itself was indecisive, Gen. Forrest himself was injured, and thus the battle represented a great strategic victory for the Union.

The battlefield offers exhibits at the Natchez Trace Parkway visitor center, as well as ranger-led tours of the battlefield. The website offers historical information regarding the battle as well as basic visitor information.

The Timucuan Historical and Ecological Preserve and Fort Caroline National Memorial is a 46,000-acre National Park Site consisting of several historical sites. The 1564 Fort Caroline Memorial recalls a brief period of French occupation during the 16th-century; and includes the Timucuan Preserve Visitor Center, which recounts area environmental history and human interaction with the environment. Visitors to the memorial can compare French fort and traditional Timucuan life. Other sites include the Theodore Roosevelt Area shell middens and nature trails; the 1814 through 1837 Kingsley Plantation; the 1935 American Beach, founded to provide African Americans access to the beach despite segregation; the Cedar Point nature area; and the 1928 Ribauldt Club, once a wintertime resort.

The memorial offers exhibits, activities to complete while viewing the exhibits, Junior Ranger activities, interpretive programs, and ranger-led student programs.

The Palo Alto Battlefield National Historic Site preserves the site of the May 8, 1846 battle which officially initiated the U.S.-Mexican War. The war was fought to determine the boundary of Texas. During this battle, Mexican forces effectively delayed the advancement of U.S. troops and continued their siege of Fort Texas. However, these benefits had a high cost in casualties—102, as opposed to nine U.S. deaths.

The site offers a 15-minute introductory film, exhibits, wayside interpretive panels, a half-mile trail, Junior Ranger activities, educational programs for students, and one-hour outreach programs for students. The film is available in English and Spanish. All educational programs require at least two weeks advance notice. The website offers elementary school and middle school teacher's guides, as well as introductory video segments for children.

The Vietnam Veterans National Memorial offers a place for reflection and personal interaction with the memory of military personnel killed in the Vietnam War. Designed by artist and architect Maya Lin (born 1959) as a minimalist sculpture with a highly reflective surface, viewing the monument requires visitors to confront both themselves and the names of the fallen simultaneously. U.S. involvement in the Vietnam War spanned 1950 (the arrival of U.S. military advisors in Vietnam) through 1973.

The site presents the memorial only.

The Brices Cross Roads National Battlefield Site commemorates the site of the battle of Brices Cross Roads in 1863. Although the battle was a resounding Confederate victory, the battle hurt the Confederacy in the long run, as it allowed General Sherman uninterrupted supplies for his campaign in Georgia.

The park offers exhibits in the visitor center located several miles from the park, along with a self-guided tour and interpretive signs at the battlefield. The website offers visitor information and a brief history of the battlefield.
