One of the harder/longer hikes in the valley, but go early because it will take a while. I normally branch off and go to Bobby's rock near the lower part of camelback and do yoga. There is parking, and information. Pretty nice they have the steps put into the trail as well. One of my favorite places to go watch the sun set. I finally did the full hike and it took about 4 hours with myself and my miniature schnauzer who is only 6 months old! He put the bigger dogs to shame. There are quite a few steep parts on this trail that have built in support bars to hold on to. I recommend using them! Watch out for joggers that like to fly up and down the mountain.. they usually have headphones on and don't pay attention to what the hell they're doing. Make sure you bring adequate amounts of water, because you will want to stop and rest to rehydrate, even on days when it is 70 degrees. At about 5/8 mile- you can veer to the left and check out the hole in the rock/ homeless guy's pad. (that's what I call it) - it is a nice little alcove and it overlooks a different side of the valley. On the way back down be sure to stay on the trail and watch for the marker signs. There are rattlesnakes in some areas in the shade, and the busier trailhead is less likely to have them. Once you reach the top, or the halfway point, or what ever your final destination is- snap some photos! It is a beautiful view no matter where you stand or sit. being 2,000 feet above sea level is pretty rad too. :-)
