We prepaid paid 22.95 on a Monday evening ... https://atlantabg.org/tickets/
Adults are $23 tues-fri and $25 on weekends. Kids 3-12 are $20 tues-fri and $23 on weekends. I'm not sure if this is a covid only thing, but if you'd like to go now you'll have to buy your tickets online ahead of time and reserve a 15 minute time slot within which you should arrive at the gardens. They didn't check ours though, and we were running about 10 mins late, but just so you know!
