This was my first time doing this hike. It was a good work out. I did the loop, which was good. It made coming back down easier on the feet and knees. I would do it again. Get there early if your going in the summer on a weekend. It's a very popular trail. I managed to get my ass on the road at 5:30am and started the hike shortly after 6:30am. There was only one other car in the parking lot when I arrived. When I came back, the lot was full.
I brought my DSLR and took lots of pictures...hence my hike time was longer than usual. The photos in this post are from my phone though. The view at the official summit was kind of crappy, but there were other spots with excellent vantage points.
