We met with our guide, Zoshia, at the gates to the Distillery District (at Mill & Trinity Street). As she was wearing a distinctive black hooded cloak and carried an electric lantern she was easy to spot. Once our group had gathered (9 guests total), our guide led us throughout the Distillery District and stopped at various points to tell us historical facts about the area, which in turn, would lead into a ghostly tale. While most of the tales were about hauntings and other supernatural events, our guide included a few non-supernatural tales of horror, such as murders that befell notorious locals.
I recommend showing up early (i.e. 7:45 PM) so you can ask to take a photo with your guide. I know Zoshia kindly accommodated my request so I have a nice memento of the occasion, even though we had to wear masks, which was an unfortunate (but necessary) shame.
With regards to masks, you need to have one (i.e. COVID-19) and you are advised to wear it while walking throughout the Distillery District. However, whenever the guide stops to tell their tale, you will have the option to remove your mask (so long as you keep a safe distance from the other guests when you do).
Afterwards we went to Scoops for ice cream. And while not a part of the tour, the tour does end near the shop and it was one of the few locations in the Distillery District that was still open that late. I was with my two sisters, who both enjoyed the tour as well and thanked me for arranging it. I should mention, we are not teens (thanks TripAdvisor for not including a simple "Family" selection).
Overall, our guide (Zoshia) was very entertaining (a real actress), well spoken (we had no trouble hearing her words/stories), and all her tales were both interesting and chilling enough as one might hope for from a ghost walk in October.
