Georgia Elephant Refuge (under construction) will be home to as many as 10 female elephants retired from zoos and circuses. This facility spans 850 acres of gentle rolling hills, lush pastures, dense forests, spring-fed lakes, creeks and streams, with a climate that will allow elephants to remain outdoors 24/7 almost all the year. It is the perfect place for elephants to regain their “elephantness” and develop loving bonds with other elephants and caregivers.
