Took a three-hour afternoon trip with Red Rock Canyon Tours in Nov 2012 - very pleasant outing and would definitely recommend it to anyone wanting a quick brush with nature. At first sight I was maybe a little bit underwhelmed - I think I was expecting a smaller version of the Grand Canyon, and Red Rock is more a large valley - but it is still beautiful. Tom, the guide, was enthusiastic and knowledgeable and is a likeable, easygoing guy. The Mercedes van is new and comfortable. Bottled water and a light snack is included in the price, and there are walking sticks for those who want to use them. All round, very good value for $59, I thought.
