I like Schenley Park quite a bit, although Frick takes the top spot for Pittsburgh parks in my book. Schenley has plenty of green space and great views as well as ample running tracks and trails, but it can also feel overcrowded and hectic at times. It's close to Pitt, so traffic and groups of students wandering loudly through the park during the Friday evening movies are common nuisances. I prefer the wooded, peacefulness of Frick, since it truly feels like you're not in the city once you get going on a few of the trails. That's not to say Schenley isn't nice in its own way though and it's certainly a cut above a lot of urban parks, so I suppose living in Pittsburgh has just spoiled me in that regard!
