I'm going to be hit the road for a 3 week trip in a month or so. I'm looking for recommendations on some good hiking trails (overnights if possible). I'm going to start in Colorado than Utah maybe hit Arizona and Cali than turn around and go see family in Wyoming before heading to Montana...

I hiked a lot in four corners area and last year molested the Tetons and Yogi Bear National Park. Looking for stuff that is off the beaten path... I climb as well so if you know about any trails that require some I'm always down (such as Subway trail in Zion...). Any caves???

Any help would be great...
