Fort Oglethorpe is a small city in northwest Georgia, a few miles south of Chattanooga, Tennessee. Its main claim on a traveller's attention is its position as the gateway to Chickamauga and Chattanooga National Military Park — the largest Civil War battlefield in the United States, preserving the site of the 1863 Battle of Chickamauga, one of the bloodiest engagements of the war.
The battlefield spans both Georgia and Tennessee, with well-maintained earthworks, monuments, a visitor center, and interpretive markers throughout. It can take a full day to explore by car or bicycle. The park is operated by the National Park Service and admission is free.
The town also has a small but worthwhile connection to military history beyond the battlefield: Fort Oglethorpe served as a US Army cavalry post from 1902 to 1946, and the 6th Cavalry Museum in one of the surviving original barracks buildings tells that story. Most visitors arrive to see the battlefield and then continue on to Chattanooga a short drive north.
