Harrison Hills Park Professional Review and Guide
"As hidden as any park can be in one of the state’s most populous counties, Harrison Hills offers some wonderful scenery and some truly challenging walking. The eastern end of the Rachel Carson Trail—a 35.7-mile pathway across the county—begins here and when connected with some other park trails, allows you to get in a good loop hike. Wildlife, particularly white-tailed deer, abounds here.
Despite having its share of playgrounds, picnic areas, restrooms, and other facilities, Harrison Hills Park is considered the “greenest”—i.e., least developed—of Allegheny County’s parks. It has a very nice network of trails that
are well blazed and easy to follow. They take you past some spectacular views of the Allegheny River and two ponds often full of waterfowl. You won’t have to battle big crowds, either."
