Little Kennesaw Mountain, Mountain summit in Marietta, United States.

Little Kennesaw Mountain is a sub-peak of Kennesaw Mountain in Cobb County, Georgia, northwest of Marietta and south of Kennesaw. It lies within Kennesaw Mountain National Battlefield Park and is crossed by a trail from Burnt Hickory Road to the park visitor center that also passes Pigeon Hill and the main Kennesaw Mountain.

The mountain served as a defensive position for Confederate forces in 1864 during the Atlanta Campaign. Soldiers built fortifications to block Union Army advances toward the city.

The mountain is marked by fortifications and monuments that recall Civil War battles. Visitors can explore preserved earthworks and trenches that reveal how soldiers positioned themselves on the slopes.

The mountain lies on a trail running from Burnt Hickory Road to the park visitor center, crossing Pigeon Hill and both Kennesaw peaks. Plan for a through-hike rather than an out-and-back, and carry water since the route is exposed in places.

The mountain serves as an important stopover for migrating birds in spring and fall. Many warbler species and woodpeckers use the forested slopes to rest during their journeys.
