Pinnacle Peak is a great moderate/easy hike if you are in decent shape. To go to the end and back is about 4 miles which was the perfect distance for us. Lots of signs and information along the way about plants on the path which I liked, and many park employees passing by as well. I went on a rainy day but it was still very enjoyable and ok to do, unlike other peaks with more rocks which get slippery. Google maps will take you to an abandoned road when looking for this- just keep driving toward the mountains and you should see signs.
