Young visitors can explore nature in an urban setting in the Children’s Discovery Garden in Sister Cities Park. Inspired by Philadelphia’s Wissahickon Valley, the garden’s winding pathways, scalable rocks and meandering stream provide a setting for discovery and imaginative play. Children can hike the trail, summit the “mountain” and enjoy the view, while connecting with the natural and man-made environments surrounding them.

The Children’s Discovery Garden at Sister Cities Park now has more play opportunities, including a playnet and platform, push-button water jets, a stream dam and a sensory-friendly twig nest. Learn more about these features in the park. The Children's Discovery Garden is opened daily from 9 a.m. to 5 p.m. 

Tunnel Log

The tunnel log in Sister Cities Park’s Discovery Garden is a feature that provides a natural play experience for kids. The log came from a fallen silver maple tree in Philadelphia that was estimated to be between 150 and 160 years old. The log was rescued from the Fairmount Park Organic Recycling Center operated by Philadelphia Parks & Recreation. It was then hollowed and smoothed out and transported to Sister Cities Park for reuse in the Discovery Garden, along with stepping stone rounds and a smaller climbing log. The tunnel log is featured from late October through April, when it is replaced by the pond.


Enjoy the pleasures of wading in the Children's Discovery Garden pond on a hot day or bring a boat or water toy for hours of fun. The pond is open April through late October, when it is replaced by the tunnel log.
