I have lived here for 28 years and never been to Chaco. It is just not on the way to anywhere. Its hard to get to, via rough washboard road. Its hot so you have to go early. I have been to Sedona on several occasions. Sedona is like dying and going to heaven. Breathtaking beauty all around you. Paved roads, hotels, B&B's, places to eat, Slide Rock Canyon (must see place to play in the water). Flagstaff is only 90 miles North so you could combine a trip to the Grand Canyon and Sedona. Southwest has a ton of flights in and out of Sky Harbor Airport in Phoenix. Chaco is flat out amazing from a scientific aspect. How they figured out all the angles and coordinates for the solstices without any tools. PBS did an hour long documentary in 2003 that was narrated by Robert Redford. Every now and then they will show it on your local PBS station. Its almost out of print on DVD but you can still find it online from a few sellers, even Amazon. The DVD is not cheap ($30) but it allows you to see the breathtaking beauty and amazement of Chaco without the long drive to get there. Lots of people seem to still make wrong turns today. There is nothing out there but Chaco, no close hotels, restaurants, food, gas, water. Very primitive to say the least. The DVD also has excellent aerial (helicopter) shots that show just how long and straight the lines are that connect even mesa to mesa. That aerial view is very important to fully understanding and grasping Chaco in my opinion. Not saying its not worth seeing, its just a "real hike" as they say!
