CO road trip

Headed up to, probably the Denver area from AZ next week. I was curious if anyone had any must see stops I should check out on the way? Supposed to spend a week up there. I was thinking of spending the night around the white sand dunes but I'm open for anything. Thanks for any help!

 

Most of the stuff is probably still covered in snow

great sand dunes is definitely worth a stop though

 

Depends on what you're looking for and the route you're planning on taking.
Sand Dunes are cool for an afternoon, but I would think not so much in March. I have only been there in the summer.
4 corners is worth a stop. And the Code Talkers BK museum. (I think this is in AZ)

Bishop's castle is epic if you're into that.
