Philadelphia's rivers and streams provide ample opportunity for recreation; events in the coming week suggest it's hiking season in the parks and refuges near the water:
At the John Heinz National Wildlife Refuge in Tinicum, there's a Summer Bird Walk on Saturday, July 9 and a Birding By Ear Walk on Sunday, July 10. Check here for the full summer schedule of events.
The Friends of the Wissahickon are sponsoring a three-mile hike on Wednesday, July 13. The hike is guided by a trail ambassador and begins at the Valley Green Inn: "Experience caves, trek the famous Fingerspan Bridge, cross Devil's Pool, discover The Spring House, Shakespeare's Rock, learn about major improvements to the trails, the history of the Livezey Mill, and other areas of the park and hopefully, spot some local wildlife."
