The City of Scranton's largest park, Nay Aug, grants residents and visitors a touch of nature amid the city landscape. Walking trails, picnic areas, kid-friendly rides, two playgrounds, two Olympic-sized swimming pools and waterslide complex number among the attractions. The Everhart Museum is also located within the park. A rock-strewn gorge and waterfalls add to the allure and have been named a National Natural Landmark. A pedestrian footbridge opened in 2007 to access parkland across the Roaring Brook untouched for many years. Nay Aug Park's David Wenzel Tree House is the first of its kind in Pennsylvania, opened on Friday, May 25, 2007. It overlooks the gorge, rising an awesome 150 feet above. The tree house was constructed by Forever Young, Inc., with public and private donations and set the stage for additional tree house construction in other cities across
the United States.
