Hi there,
Thanks again for all the advices and recommendations: we had a tremendous holiday!
We visited:
Birds of prey world center in Boise
Snake river canyons and Shoshone Falls in Twin Falls
Flaming Gorge on Green River in WY
Dinosaur Monument Valley in Vernal UT
Harper's Corner and Colorado Monument in CO
Arches Park and Canyonlands in Moab
Grand Canyon
Sedona
Lots of awesome hikes and we rented a jeep in Moab for 1 day, which allowed us to go see stuff only accessible by trails and get away from the crowd.
As we are waiting for our return flight in PHX, I wanted to say that your country is truly beautiful.
Thanks again!
PS: and you were right, the heat in Phoenix is brutal
