Rocky Mountains big loop tour - Denver, Yellowstone, Utah, Las Vegas, Colorado, Denve

[JohnYeldham]

I am planning a road trip for next year (yes, I realise this is a long time in advance), probably end of September to October, for 3 weeks.

Rough plan would be something like this:

Denver to Yellowstone, through Utah and the National Parks, to Las Vegas, back towards Colorado via Grand Canyon and other New Mexico sites, and doing the interesting places in southern Colorado.

Is that do-able in 3 weeks? Google says 49 hours driving! I am happy to have long days driving, but regular no-driving days are a must.

Any suggestions about what we should and shouldn't visit?

cheers for any help

John
