Atlanta on the Cheap lists Trick or Treat Week in downtown Decatur for Thursday, October 29, from 10 a.m. to 8 p.m., with free participation. Unlike a single two-hour party, the long window allows families to visit when the children are ready and the schedule permits.
The useful part is flexibility. A walk around downtown Decatur can combine a little Halloween activity with dinner or a snack. Exact participating storefronts and treat availability can vary, so do not assume every business on the square is involved.
If today’s afternoon is crowded, the city’s Boo Bash in northwest Atlanta is a more concentrated 3–6 p.m. event. Decatur is the better option for a casual visit with less precise timing.
Check participating Decatur businesses and pick a convenient hour rather than committing to a late-night event.
