Awesome hike on Cholla Trail! Go during holiday season because you will catch Santa with a Christmas Tree passing out candy canes at the top of the mountain!
I found the climb up to be more challenging despite what others have said because when I went down I was used to the pace and momentum of the mountain and therefore made better time. However, it's a good idea to not get overconfident because the rocks ARE slippery and I fell a couple times, which was more funny than anything else. But it's good to be aware of that because I was fairly careful throughout the hike and still managed to lose my balance on a couple rocks.
Ultimately, it's really important to be prepared with good shoes and at least two water bottles! And have fun!! The views are gorgeous!!
