I hiked Pinnacle Peak 7 days in a row from July 12 - July 18, 2005. This was a "hot spell" with the temperature being 92 at 6:00am so I hiked at 5:30 in the morning except for one day when I slept in...started the hike at 10:00am and the temp got up to 116! The life savers here were the broad rimmed hat and the camelback water backpack which holds about 35oz of water...which was all gone by the end of the hike. If you look at the three photos....first one is of me at the top of the mountain...second one was looking at the sunrise while being about 3/4 of the way up; and the third photo is of a dead snake on the trail...I stuck my foot in the photo for size comparison. The hikes each day were fantastic...looking at the multi-million dollar estates is breat-taking....as is the view of the mountains and city. The round trip is stated at 3.5 miles but once you get to the bottom of the mountain, you can continue on a path to a fence which will then make the total distance 4.0 miles.
