About Barker Spring
Barker Spring, Georgia is a free, undeveloped geothermal spring located in Upson County near the community of Hannahs Mill in the Piedmont region of central Georgia. The spring surfaces at approximately 73 degrees Fahrenheit, roughly 9 degrees above the regional ambient groundwater temperature. Thomaston, the Upson County seat, is the nearest town with full visitor services and sits approximately 10 miles to the southeast.
The spring gave its name to the small rural community that grew up around it. Georgia has only seven documented thermal springs statewide, making Barker Spring one of a limited number of geothermal features in the southeastern United States. The spring emerges in the Piedmont geological province, where thermal activity is modest compared to the volcanic and rift-driven systems of the western states. This is one of the few natural hot springs in Georgia accessible by road.
There are no constructed pools, changing facilities, or managed access at the spring. Visitors encounter a natural geothermal seep in a rural landscape, best understood as a geological curiosity rather than a recreational soaking destination.
