The State of Georgia makes available this PDF chart addressing accommodations, activities, and accessibility of Georgia State Parks.
There are ADA Assessments for all of Georgia Parks trails. “These accessibility assessments are maintained at each state park and historic site where the trails are located and are available for review and/or can be provided electronically by directly contacting the state park or historic site office. For further information, contact Larry Blankenship at 404-656-6524.”
