Entrance to the park is FREE!!!
South Mountain park is the largest city run park in the United States. Drive down Central Avenue and take the roads all the way to the top of the mountain at Dobbins point, Buena Vista look out and TV towers. It's free to get in and the gates to get in close at 7 PM but you do not have to leave the park until 11 PM. The road up and around the top of the mountain is a sports car/motorcycles dream (or nightmare if you go over the cliffs).
Fantastic mountain for hiking during the day or night time hikes with city views. Granted this mountain is not as private and desolate as the superstitions but it is 10 times better than hiking Camelback with 350 other people on the same trail. I have hiked all day for 15 miles and never ran into a soul all day (which is what I want when hiking).
Multiple access points to the mountain are located all around the perimeter.
During the spring south mountain has a spectacular array of desert wildflowers blooming on it... Get out and take some lovely pictures!
