If you enjoy hiking with a beautiful view of the city, you must make the short trek on each side of the mountain (Cholla and Echo) at least once. A warning though, this is not for non-active, non-adventurous people. if you are not prepared to go up some boulders and use your hands, this can be dangerous for your ankles. The mountain is a beautiful city landmark, with a 360 degree view at the top.
However, this place will not get a pass from me, because the city really needs to figure out the parking situation. I understand you don't want too many hikers on the mountain at the same time, but this has about 1/3rd of the parking that would be optimal. On the Echo trailhead I waited for 45 minutes twice on a weekend just to park and didn't return after that. The Cholla side has parking that is a 15 minute walk from the trailhead and you may also have to wait for parking as well on that side.
