Bison Encounter (Yellow stone)
Monument Valley, UT
Be prepared to hike to see delicate arches & the landscape arches, both are must see attraction take sufficient water you will be just fine. Btw, don't forget your camera ...
Delicate Arches (Arches National park)
Flew from San jose to Salt lake city, short flight saved quite a bit of time and effort to drive locally around. Covered Yellowstone in 2 days, monument valley for a day and approx. 1-2 days in arches. Being said that each of these parks needs a dedicated visit of 2 - 3 days each, these are fascinating park as you drive around the parks you will discover more and more interesting vista points and hike trails. Wish I had more time, sometime you need to be happy with what you got. Yes I got good pictures, check it out - http://500px.com/senthilb or www.nizhalpadam.com (Facebook page)
