Take all the back roads you can. More fun and way more scenery. How much time do you have? All summer!?
Head to Flagstaff, up to Durango and yes north on the Million Dollar Highway(2 lane mtn road!) Into Delta to Paonia to Glenwood Springs, then east on 70 through Glenwood Springs Canyon (yes the best slab ride) and if you have time head north from Silverthorn (gas up) on 9 to Walden (gas if you are below 1/2) I think it's the 14 into FT Collins for @85 miles of twisties. So many roads to take. Take your time and enjoy the scenery.
Be sure and ride through Rocky Mtn Park and Estes Park and so much more. How much time did you say you have (not said above) .

Well Boulder is a great base of operations for day rides. Nederland, Gold Hill and a slew of old mining towns along the Ridge Road

If having to ride I70 which is purdy, take the road from Idaho Springs to Golden along the river to get to Boulder. Stop in Idaho Springs for a short break.
