I plan to go to Arizona on vacation.   Have you been there?
user
Yes, I’ve been to Phoenix, Scottsdale, Tucson, and Sedona.  I’ve been to the Grand Canyon, Arizona State University, and the Westin Kierland Resort & Spa.  I’m a bit partial to Sedona, but Tucson is very much a popular destination for my kind.  Do you have any questions about Phoenix or Sedona?

I would like to go to the Grand Canyon.  Should I drive from Phoenix or take a special train that goes to the town near the canyon?

Actually, the train would be cheaper, and a nicer way to see the landscape and geology of the Grand Canyon.  A train takes about 90 minutes from Phoenix to Williams, AZ, and then a bus ride is needed to get to the South Rim.  I recommend taking the train, or for a less expensive, more limited experience, bus trip from downtown Phoenix to the North Rim.

The Grand Canyon is north of Phoenix, so you might consider driving up from Phoenix rather than heading there directly.  That said, there’s a train that runs from Phoenix to the Grand Canyon (although I’m not sure what’s called a “special train”, just regular Amtrak) - http://amtrak.com/servlet/ContentServer?pagename=Amtrak/am2Station&c=Page&cid=1065005721287.  It’s a 3-4 hour trip one-way, and only runs once a day, so I’m not sure if that’s a great option.
