I almost don't want to write this review because I love how empty it is.... But also there are so many trails broken off from the 32nd street trailhead (parking is not easy because there are less than 20 spots) but it's my favorite hiking spot close to home.
There are hilly trails that you can run but also a few trails with some good incline so there's a little for everyone. I like it because it's not nearly as busy as Squaw Peak's main trail (which you can actually get to from the 32nd st trailhead) or either of the Camelback trails.
Also, dog friendly!
