After Zion, we plan on visiting Bryce Canyon, Arches, and/or Canyonlands National Parks. I was surprised to learn that southern Utah is home to the largest concentration of National Parks.
On our way into Colorado, we're going to try to visit the cliff dwellings at Mesa Verde. Then we'll spend five days in Estes Park, with several trips into Rocky Mountain NP.
I figure I need to experience these natural wonders while I still can. ;) And I plan on taking plenty of photographs. If you have any tips for me -- or know specific sites I should see on this route -- let me know!
