Frick Park At 644 acres, Frick Park is Pittsburgh's largest historic regional park.

Although Henry Clay Frick bequeathed the original 151 acres to the city in 1919, the park did not open until 1927 after additional land had been acquired. Most recently, 106 acres were annexed to the park as part of the process that created the Summerset at Frick Park housing development and restored the Nine Mile Run stream valley. Today, Frick Park stretches from its northern borders in Point Breeze down to the Monongahela River.

Birding enthusiasts love to visit Clayton Hill, where more than 100 species of birds have been recorded. Children flock to the famous Blue Slide Playground and learn about nature at the Frick Environmental Center. The park also features red clay tennis courts, baseball fields, and the only public lawn bowling green in Pennsylvania.

The Pittsburgh Parks Conservancy has completed extensive ecological restoration work in Frick Park since it's first capital project in 2000, the restoration of Reynolds Street gatehouse entrance. The Parks Conservancy, in partnership with the city of Pittsburgh, opened the new Frick Environmental Center to the public in September 2016, and in 2018 it was certified as a Living Building, achieving Leadership in Energy and Environmental Design (LEED) Platinum status.
