This is a great place to do some easy walking/hiking. Not nearly as strenuous as Piestawa Peak and not as crowded.
The area is clean and the air is fresh. Plus, there is a good chance you'll see some wildlife (hawks, rabbits, insects, ect.). Plenty of parking and a few ramadas with picnic tables.
-1 star because, at points, you can still see the highway... but once you get past the first couple hills it's like you are in the middle of nowhere.
(Directions: Exit the SR-51 at Northern and head east to the parking area. The Yelp map shows the incorrect location.)
