Aguja Celo Rey 

This route totally rocks! The top of the spire is incredible, as I recall, only about 2 people can fit (maybe only one). If the wind is up, then communication with your second sucks at the first belay. Bring some longer runners to avoid rope drag. Also, note that this route is 8 bolts for the 110 ft - as I recall, the bolt spacing is not even, and I would suggest a smaller cam for the first pitch before the crux (somebody else might have some better beta for this).

For pitch one, you might feel compelled to try the crack where the saddle between the spires forms, but stay on holds to the right and you'll have less trouble. Some of the old, hand-made pins remain from the Mexican first ascentionists.

I brought a set of stoppers for pitch one and placed two of them. Also, I found the crux to be the dark pod/offwidth directly behind "Nick" in the photo above. I cut out onto the face once the offwidth tapered off (maybe 4/5 feet above bolt?). I also clipped some bolts off the arete of the "looking glass" hole beneath the saddle before heading back onto the face. Seemed to be the logical line, and couldn't figure what other route those bolts could have been for. Great route, both pitches are stellar!

Super Fun route to access the top of the Small Spire! The First pitch is slightly run out between higher bolts but if you bring a longer sling there is a thread through you can do to reduce it, regardless the climbing is over easy terrain. Second Pitch is unreal!! First time I climbed a spire and it was everything I imagined and more!! Go to the Summit proper for some exciting exposure, but watch out for the cactus!!!
