The trail starts pretty level and takes you to the edge of the Granite Mountain Wilderness Area where there is a board with information about the area. There is also a sign-in / sign-out sheet so that the Park Rangers can know if there people on the Mountain.
Once you reach the intersection of the summit trail with Little Granite Mountain Trail #37, you take a right through the gate and start heading up the mountain.
Here you see the effects of the Doce fire from 2013. I wish I had done this trail before the fire - it must have been incredible!
Once you reach the summit, you can definitely tell how high you have climbed (over 1500 feet). You have a great view of Granite Basin Lake below and the vast Prescott area. Even Thumb Butte looks just like a bump on the horizon (far upper right of the photo below).
