Man, I love this hike more and more every time I do it. It's a bit of a challenge and be prepared for some rock climbing closer to the tippy top on Cholla Trail. Echo is steeper but the view at the top is always worth it! So make sure to have you're camera with you. You don't want to hike all of that without getting a picture to represent your hard work!!!
If you're going to attempt to go on a weekend, make sure to wake up early. Finding parking and the walk to the trail head will take extra time. But be prepared, it will still be busy.
Happy hiking and wear good shoes!
