So let me start off by saying I'm almost 55 and not in great shape. I was traveling with my 16 year old daughter. The hike at Red Rock Canyon was a challenge for me. I survived but it was difficult. Would I do it again? Yes! It's amazing! Would I do it again in September? No! It was sweltering hot - triple digits! They provided plenty of water for us. Phillip, our driver and guide, was even a great photographer. Would I do anything different? Just change the time of year because September is way too hot! 113 degrees is brutal!
