I made some initial observations and reached the base of the summit approach route a couple years ago. I’ll return some future Spring or Fall soon to complete and document this summit approach.
Take the Charleston Blvd. exit off Hwy 215 (at Red Rock Casino) and head upward as Charleston Blvd. becomes Blue Diamond Road above Hwy 215. Pass through the residential area and continue to follow signs to Red Rock Canyon NCA. Take the Calico Basin turnoff (right) about a mile before the Red Rock Park turnoff. Continue to the very upper end of the road where there is a large parking area. This is your starting point.
