Philadelphia Zoo

Philadelphia Zoo is located at the corner of 34th Street and Girard Avenue in Philadelphia’s historic Fairmount Park.

PARKING: IDF will cover the cost of parking for all IDF Walk for PI participants.
Zoo parking is available in several lots and the Zoo Parking Garage along both Girard Avenue and 34th Street. Handicap spaces and spaces for vans are available in both Tiger Lot and the Parking Garage.

PUBLIC TRANSPORTATION:  The Zoo is just two miles from downtown Philadelphia and public transportation is available using SEPTA, which runs bus and trolley routes to the Zoo area.

Be ready to hear from inspirational speakers during our opening ceremonies, grab a continental breakfast, and visit our sponsor and activity booths. We'll have special buttons available for those diagnosed with primary immunodeficiency (PI) and their close supporters, and make sure to fundraise $125  to qualify to receive a Walk for PI incentive t-shirt. 
After you finish the walk, you can enjoy the Philadelphia Zoo with family and friends. Zoo admission is included with walk registration. Philadelphia Zoo is home to nearly 1,300 animals, many rare and endangered.


Wear your shirt with pride! Participants will qualify for a Walk for PI t-shirt when they raise $125. Be sure to mark your t-shirt size when you register.  

Raising $125 ensures that we can not only cover the cost of our walks but also increase what the Immune Deficiency Foundation (IDF) can achieve to improve the lives of those living with primary immunodeficiency (PI). Because of your support, IDF can continue to provide educational resources and programs at no cost to individuals and families, power critical-patient focused research, and lead the way in the fight to improve diagnosis and access to treatment. 

Be sure to check out our Fundraising Resources for tips and suggestions on how to fundraise in your community and on social media! 

While there is no fundraising minimum, participants are encouraged to raise $125 and more. You will receive recognition gifts when you meet certain milestones. By participating in IDF Walk for PI you agree to the Immune Deficiency Foundation to use photos, video, film related to this event for legitimate purposes. This includes but is not limited to photos and videos sent to the IDF and tagged on IDF's social media.
