There's no shortage of ways to get to amicalola easy.
REI in Atlanta runs shuttles.....numerous people shuttle....public transport gets you to gainsville where taxis wait....
There is however, a plethora of people too lazy to use Google who want every answer spoon-fed.
Gatc site has the best info, very odd it come up first if one Google's" getting to Amicalola from atlanta". Yet the question is asked here frequently.
No wonder so many can't make it out of Ga, they can't figure out how to get to trail head without assistance.

Good luck with Uber in a small town of 3000. They have taxi though that will take you. You won't save any money, while just making things difficult. Spend night?
Mant thru hikers are too young to rent a car anyway.
You MIGHT find an Uber. It's not something you can count on in rural areas. Taxis are same...you might wait an hr for pickup. A prearranged shuttle....is reliable and on time.
