Before I start giving specific locations and addresses and tips, I have to put out there that some of these locations are on private property. If there are signs, please obey them. You can see perfectly from the road, or your car. Some of these locations are houses where people live; don't go on their lawn, knock on their door, or sit on their stoops. Be respectful and polite.
Also, I've tried to put these in a logical driving order. But Senoia, Grantville, Newnan, and Haralson are all within 20 minutes or so of each other. So if you end up going in circles, it's a beautiful area and not the worst thing you could do.
Spoilers ahead...
Atlanta:
CDC Building -
2800 Cobb Galleria Parkway
The building portrayed as the Walking Dead's CDC is actually Cobb Energy Performing Arts Center. Clean up the dead bodies and add some flowers and it's a pretty beautiful building.
Terminus -
793 Windsor St
This is all private property, but if you drive to the very end of the street, before it takes a hard left, you have a perfect view of where the group first enters Terminus and sees the large letters spelling out the compound's name.
Rick's House -
817 Cherokee Ave SE
Episode 1.1 "Days Gone By"
Someone lives here, and it's not Rick...stay off their lawn!
Morgan's House -
386 Ormond St
Episode 1.1 "Days Gone By"
This house is just a couple of blocks from Rick's. Someone also lives here, be respectful.
Newnan:
Woodbury Fighting Arena -
57 E Broad St
Use the above address to get to Caldwell Tanks, but then find the corner of Perry St. and Salbide Ave. There's a small parking lot there and you can look over the fence and see the exact area where the fighting arena was staged.
190 Lagrange St.
Episode 2.3 "Save the Last One"
This is actually Newnan High School, so be careful where you go. You really only need to go down Waterworks Rd beside the school, and you can look up the hill where Otis and Shane made their initial run.
Merle and Michonne (Oaks Inn) -
1057 Highway 29
Episode 3.15 "The Sorrowful Life"
Merle captures Michonne and on their very long walk he stops and ties her up at a motel, almost getting her killed by walkers. People live at the old Oaks Inn, so be nice.
Senoia:
Woodbury -
Main St
Main Street Senoia is The Walking Dead Headquarters. First make a stop at Senoia Coffee and Cafe for a delicious meal or some Zombie Dark Roast coffee. In the show, this shop sat just outside the walls of Woodbury and was called the Woodbury Coffee House. The business sign that adorned the building during filming is now inside the cafe, along with some other cool memorabilia.
As you head up Main Street don't look for the Governor's House, he burned it down. It is currently an empty construction lot a couple doors up from Senoia Coffee. Cross the street and pop into The Queen's Jewels for a fun zombie bracelet or necklace charm.
Continue another block or so and you'll come upon The Walking Dead Store. Either leave your wallet in the car, or be prepared to spend. They have everything! Even if you aren't in the mood to shop, head downstairs toward the back of the store to see some genuine props from the show, as well as the messages cast and crew have left all over the walls. Fun reading! If you're lucky, you might run into a walker inside the store. Michael Jaegers, who has played several zombies throughout the seasons, and Kathryn Telford, another of the undead, were there signing autographs and taking pictures. Both incredibly nice! Then for a quick pick me up, head next door to The Waking Dead Cafe (I didn't forget an L...it's waking...like with caffeine...coffee...okay...).
Alexandria -
If you go back to the bottom of Main Street (the bottom of the hill) and turn around, you should see the walls of Alexandria. You can cross the railroad tracks and look from there, but don't bother crossing the street. There's a guard and they don't like that. So all you'll see is the wall, and some of the burnt out buildings that sit outside the wall. Be respectful; breaking the rules means you're disrespecting the show itself.
Rick and Carl's Safe House -
291 Plyant St.
Episode 4.9 "After"
With Rick barely able to walk, he and Carl hole up in this house. Rick collapses on the couch, Carl has a screaming fit...then leaves to find pudding.
Pudding House -
239 Plyant St.
Episode 4.9 "After
Carl finds pudding and loses his shoe to a walker. Not a bad day, overall.
Church with No Steeple -
Luther Bailey Rd.
Episode 2.1 "What Lies Ahead"
I don't have an exact address, but the church is on Luther Bailey Rd, not far after turning off Old Hwy 85. It's closed now, but still be very respectful. The gang runs through the cemetery out back (which you should not do), and enters through the front doors. Shane then proceeds to argue it's not the right church because it has no steeple...
Haralson:
At 10 Line Creek Road you'll find Cherokee Rose Retail, which runs the Walkin Dead Tours - and this one looks fun! Before they take you out to the Esco Feed Mill filming location, they'll equip you with a replica weapon of your favorite character (Merle, Daryl, the Governor, and even Neegan) and take you out for some really fun photo ops.You'll also get to go into the Mill to the Governor and Rick's negotiation table. You'll see a lot more filming locations with this tour, and I'm sure have a blast!
If you can't tour with them, check out the shop. It's packed full of fun merch and even some genuine props, such as the chairs the Governor and Rick sit in during their negotiations. It's a must stop before heading down the road to the Mill.
Esco Feed Mill -
23 Line Creek Rd.
Episode 3.13 "Arrow on the Doorpost" & 3.15 "The Sorrowful Life"
After turning onto Line Creek Rd, turn onto the second little street on the left. In front of the second building on your left is where Daryl kills Merle, right there in the grass between the building and the road you're on. This is all private property; you can drive all around it, but don't go on it.
Sportman's Deer Cooler -
44 Addy St
Episode 3.1 "Seed"
This building is only seen briefly as Michonne enters the front door. She and Andrea are resting here while Andrea is sick. I didn't go inside...because there are deer antlers nailed all over the front wall and I was scared.
Grantville:
This town was used to film three episodes, "Alone", "Clear", and "Prey". As soon as you get to Main Street you'll easily recognize it as the town-size-booby-trap Morgan creates in "Clear." While you can see locations on your own, I recommend that you do take a tour here with Z is for Zombie. Find the building on Main Street with the Zombie sign outside - that's the place to go.
30 minute tours are offered daily for just $10, and on this tour you'll learn lots of behind-the-scenes information on what filming was like for the small town and you'll get to tour inside Morgan's apartment. The apartment has been recreated to mimic how it looked in "Clear" - animal cages, weapons, crazed chalk ramblings all over the walls. In short, it's awesome. The tour guide, Rebecca, is lots of fun and very knowledgeable. If you have some extra time, on Saturdays at 4:00 join Rebecca for a viewing of "Clear" before taking an hour long walking tour. Rebecca also has some one-of-a-kind, original merch for sale that is awesome; I recommend her "Watch out for Lizzie" products!
Morgan's Apartment
Episode 3.12 "Clear"
I'm not sure of the exact address, but it's on Main Street and you can't miss it. The blue front door is where Rick and Michonne enter and of course the roof is where Morgan perches to shoot.
The other picture is from inside Morgan's apartment, which you can only visit by taking a tour.
Grant St.
Episode 3.12 "Clear"
If you're facing Morgan's apartment and turn around, then slightly to the right, you'll see the Grantville Freight Depot, a long white building. If you stroll down Grant Street you'll see a Cafe sign; this was made into the entrance of King County Cafe, where Carl retrieved a family photo for Judith and Michonne found a paper miche cat that was just "too damn gorgeous" to leave behind.
McKee Building
Griffin Street
Episode 3.12 "Clear"
On the next street over from the Freight Depot (you can see it from the Depot) is McKee Air. When first entering town, Rick peers around this building to see if the coast is clear. Coast is...clear...get it? Ok, I'm done.
Away With You Wall
Main Street
Episode 3.12 "Clear"
At one end of Main Street you'll find the wall where Morgan painted his cheery message 'Away With You.' While the message is no longer there, the wall is awesome. Honestly, it's an awesome wall without The Walking Dead associations. If you walk inside the wall though, the nice townspeople have re-painted Away With You for some fun photo ops. Disrespectful people (not like any of you reading this) have torn away at the wall to have keepsakes. Bad. If you want a keepsake, you can buy a brick at Z is for Zombie. This will also help preserve the wall, which, thanks to naughty tourists, has already cost the town $1,000.
The Baby Store
Corner of Colley and Legrange
Episode 3.12 "Clear"
The building with the copper-colored awning served as the Baby Store where Carl and Michonne fetch a crib for Judith.
Funeral Home
26 Magnolia Ln
Episode 4.13 "Alone"
Although not really a funeral home, this huge house served as one when Daryl and Beth needed a place to stay. Daryl eat pig's feet, Beth eats peanut butter, and they find a one-eyed dog.
Cemetery
Griffin St.
Episode 4.13 "Alone"
In the episode it looks like the Funeral Home sits on a hill behind the cemetery that Daryl and Beth walk through. They're actually a couple miles apart. The gravestone they stop and put flowers on does not exist, it was added for filming. Turn into the cemetery at the first entrance (if you're coming down Griffin from Main) and drive to the end, then turn right. At the end of that section of road is where Daryl and Beth come out of the woods.
Well, that's it...almost. Just two more things.
1. If you find on other sites the locations for the Elder's Mill Campsite (where the group camps after fleeing the farm) or for the Bellwood Quary (from season one), you cannot actually get to either.
2. If you want to find the pharmacy where Glenn and Maggie...look for "stuff", or the bar where Hershel drowns his sorrows, here are the addresses. I just ran out of time.
Bar - 132 Terrentine Rd, Sharpsburg
Pharmacy - 105 Main St, Sharpsburg
