This is the rightmost of the church spires when viewed from the parking lot. The standard route is a (somewhat adventurous in my mind) 4 pitch 5.7 climb. The climbing is mostly easy, on occasionally dubious rock, with a few short sections that seem a bit stiff for 5.7. The main attraction in my mind is getting to the summit of an impressive looking pinnacle at a moderate grade, rather than any great climbing. This would be a good climb for the summer, as it is largely shaded.
From the intersection of route 89a and route 179 in Sedona, take route 179 south for 2.9 miles. Make a left off of 179 onto Chapel road. Park somewhere near the end of the road by the Chapel (note that some of the parking lots are just for people visiting the chapel. about 100 yards before the chapel, the "Chapel trail" takes off towards the rocks. This is your starting point. Take the trail for a few tenths of a mile, passing a cylinder of rocks encased in mesh wire, and a short section of walking on bare bedrock. Take a gully up to the left, passing a few cairns. Scramble up a short band of cliffs/slabs, and traverse right across some slabs to come around the front of Christianity Tower (the 2nd tower from the right). Head up a gully to the notch between Christianity tower, and Streaker Spire. This should take roughly 1/2 hour.
Be careful not to park in one of the lots that are specifically for people visiting the Chapel. I read on mountain project that parking might be difficult. This was not the case when I was there on a nice Saturday in mid-march.
