Granite mtn. Is a really cool place with excellent crack clmbing. I'm not sure about camping though. I have climbed there in early January in short sleeves but, of course, I'm sure the weather could go either way. It looks pretty good right now although just a little cold at night. It seems like Prescott has a lot of other climbing to offer as well, but you could spend a good little vacation just at GM.
Most stoked on crack climbing up to 5.11. Looking to camp as that is the cheapest, and preferably staying in one location.
Sedona & The Waterfall would be a great place to climb then. You can camp in mild temps for free nearby. The Waterfall has some great cracks in those grades.
Sedona also has great cracks, both cragging & MP. Let me know if you need any more info.
