Next, continue East on Rudasill to Tula Ln, then Left (North) to Picture Rocks Rd. Turn Right there and then turn Right into the Cam-Boh parking area. On the NW side of the parking lot is Sidewinder Trail which should take you across Picture Rocks Road and then about 0.1 miles to a Crested Saguaro. I actually did not see Sidewinder Trail and just went straight across the road from the parking area, went behind the sign there, less that 0.1 miles to the Crested Saguaro.
