Walking tours (meeting place not listed on the tours page)
We do not have a meeting place for this group yet.
Your first visit
Feeling unsure the first time is normal. Most groups are glad when someone new walks in.
First step: Read the articles on the home page, then email the tours coordinator, Alison Zeidman, at azeidman@hiddencityphila.org to ask which walking tour fits you and whether an individual can join one..
What to expect
The tours page names four walking tours and says they can be booked as private tours for groups of up to 30, but it gives no meeting place, length, or price. The simplest start is the publication itself, whose articles cover preservation, architecture, development, and city history.
Tips for your first visit
- Ask the coordinator for the meeting place, length, and price before you plan the trip.
- Members get 40% off Hidden City events and tours, and invitations to members-only tours.
- Membership questions go to the program director listed on the contact page.
Newcomer welcome
Fine for newcomers, but you may need to speak up (3 out of 5). Why we say this: The articles are public and membership is optional, but the tours page describes group bookings and gives no public tour dates..
