The Grand Canyon is an amazing natural wonder. Thankfully my husband and I planned ahead for our visit. We were staying in Scottsdale, AZ and knew the temperature at the GC could be 25 degrees COLDER and it could be windy. It had snowed 2 days prior. We had warm, layered clothing, down jackets, hats, gloves, and boots. Two other people on our tour only had sweatshirts -- they had to buy fleece jackets. Viator connected us with Arizona Scenic Tours and the owner, Steve, and our tour guide, Mike, were terrific. They specialize in small groups, so no headsets were needed. They fully explained the long drive to the GC, the stop at Montezuma's Castle, the short stops to eat on our own and fit in as many GC rim overlook stops as possible. Mike definitely knew the ins and outs of the GC and how to avoid the crowds --- and he was spot on. It was a 13-hour trip but the conversation never waned and Mike filled the ride with a vast amount of stats and enlightening information. We thoroughly enjoyed the day.
