3 Week Denver-Moab-Idaho Falls-Yellowstone-Denver Loop : Advice Please?

[BlackrazorNZ]

It's a bit like asking whats best, Apples or Oranges ? ;-)

We all know the answer is Oranges, right? :D

Having said that I would add a night at Moab so yyou could explore part of Canyonlands and Dead Horse point.

Just googled both, they look awesome, added, thanks!

Instead of going to Cheyenne and then spend days in Denver consider going to Estes park to 'chill out'.

Also googled, also looks nice, added :)

As SLC is no longer in your plans, have you considered heading north from Moab to wards Vernal and up through Rock Springs on US191 to Jackson WY. With an overnight on route you could visit Dinosaur NM and/or Flaming Gorge Res and it's a lovley drive.

Looks nice but would add a lot more drive time - but I'll do some maths and see if putting Jackson before Idaho Falls would work.

As has been said, Yellowstone is huge and the going is slow so consider more time there. If you don't plan to stay in the park then you could also look at West Yellowstone for a night to explore the nearby attractions, although you can get reasonably priced cabins in the park which is well worth it imo.

I've messed with the schedule to stay 2 nights in Gardiner - it's not long but hopefully enough for a taster.
