Redstone Tours, Scottsdale

Much of America's southwest is painted with shades of a single color: red. Bright crimson, dark maroon, and everything in between define the landscapes from Sedona's towering rocks to the the Grand Canyon's deepest points. These are just two of the destinations visited by Redstone Tours.

It's fitting that the company's name harkens to the region's rocks, since it was founded by a geologist. With a scientist as their inspirational leader and boss, the guides teach groups about the area's natural history as they lead them past the likes of Cathedral Rock and answer questions like "just how old is the Grand Canyon, and what does it want for its birthday?" Redstone Tours also leads tours of Native American sites and takes groups on rafting trips down the Colorado River.
