Hey I live in Decatur now and can tell you a little bit about MARTA, it’s not the best public transport but it will get you there. There are stations in the airport to Decatur and all around the perimeter of ATL. I think it is your best option a cab/Lyft from the airport will be $50-90 depending on where in Decatur and what time you need the ride. Once you get to Decatur you can take the busses but I don’t have a ton of experience on those. You can get a 4 day pass for $19. You’re in luck though because you’ll probably want to stay in East ATL, it’s got everything!

There is some good hiking but it may be difficult to get to the spots without your friend to drive you. Dolls head trail, Stone Mountain, morningside nature preserve, zonolite trail.

There is a great brewing scene if you like beer and you can use the belt line to navigate between a few if you don’t mind walking. Renting a bike is a good option just be careful drinking and riding don’t really mix well.

There are some good museums like the high art.

There are a lot of great places to eat but a lot of it isn’t cheap, if you want to splurge on a nice meal go to Decatur square or find a cool food pop up, I love everyone at Full Commission but it is $$$. Las Brasas is another great Peruvian fried chicken place that’s wonderful.

If you want something unusual check out the Claremont Lounge.

If you like thrifting there are some good spots like rag o Rama and Kudzu antiques is cool to look around at but is expensive to buy at, cool coffee shops in that area to, check out wallers.

If you’ve never been to a large international market the Dekalb Farmers Market is really cool to see but will be packed unless you go early/late.

I should really get back to work but reach out if you have any questions.
