This is from plans for a trip we are making out to the area this spring...

If you like riding the rails, the Verde Canyon RR is too good to miss... http://verdecanyonrr.com/ in Cottonwood just east of Jerome.. Of course the entire 89A (alternate) route passing through Sedona and Jerome is prime for some slow cruising and sightseeing.

89A out of Flagstaff at a minimum down to Prescott, and possibility all the way down to Congress, Az is in my book a must drive route. This area is called the painted desert for the colorful rock formations in the area.

Another RR ride possibility.. the train from Williams to the Grand Canyon.. Have you made reservations at GC yet? Price and availability might become an issue. An alternative would be to stay in Williams and take the train up to the GC and back.. http://www.williamstours.net/?p=1

On the your way out there coming east on I-40, a stretch of the old Route 66 out of Kingman at I-40 Exit 53 that runs through Hackberry, Peach Springs, and goes by the Grand Canyon Caverns (a must see if you like caverns) Seligman, and pretty much ends at I-40 Exit 139. This stretch of 66 parallels the Burlington Northern Santa Fe railroad..

If you have a Garman GPS this route is in the map data base. With detailed maps of the area, highly recommend getting off the interstates and travel the local scenic roads in the area.

Petrified Forest is to the East out of Holbrook.

Our destination for the drive out is Tucson.. so the aviation boneyard and possibility the Titan Silo are on our list.. There's so much stuff down there, the Saguaro National Parks East and West, Karchner, and many others, we will have to pick and choose based what time will permit..
