  Majestically framing the west side of the valley, Red Rock Canyon is the most notable natural treasure in the Las Vegas area.

  Commencing just before sunset, run through Red Rock Canyon while enjoying the stunning sunset as day falls into night. Sun is replaced by stars and moonlight guides the way. The omnipresence of the surrounding canyon under the moonlit starry night is magical! Joshua trees dance in the shadows and the neon lights of Las Vegas can be seen in the distance. An enchanted late summer evening run.
