I am torn on Highland park from time to time because I cannot walk my pooch around the little resevoir lap near the main entrance. But it boasts pretty fountains walking trails or a paved road to run on if you prefer. So four it is.
Also it has this awesome castle looking playground, I want to run and jump on but I am childless and probably cannot take my dog on there. So i resist the temptation.
Highland park is sizeable for biking, hiking, and also borders the fabulous Zoo, I also find it to be a little less crowded than Frick on most days, parking is along the park loop so its easy. There is a swimming pool here and, it is a dog friendly on leashes park.
This is also a fabulous neighborhood to grab coffee or lunch in after a nice midday stroll.
