Great hike! We went on a rainy day in Feb and it wasn't too crowded (I hadn't done it since moving to AZ a year ago because I heard it was brutal in the summer and crowded in the winter).
Pretty great views (which I didn't expect having moved to AZ from San Diego/San Francisco and only being impressed with ocean views). The foliage on the trail was lovely too--iconic saguaro cactuses.
It was a little scary since the jagged rocks the top 1/4 of the hike to the Summit were super slippery, so we had to take our time.
