I discovered Cottonwood Canyon park after doing an internet search for the best walking trails in Las Vegas. Plenty of parking was available upon arrival and departure on the Sunday afternoon I was there. It appeared that the parking issue stemming from the rehab center had been addressed as there were plenty of people parked in the street in front of the center but plenty of spaces were still available in the lot for the park. The park itself was very nice. Had a nice paved path to walk on and was very clean. There was the occasional evidence of people not taking the responsibility to clean up after their pets but overal very well maintained. I give this park 2 thumbs up for both human and dog walking.
