All 3 are awesome but Mt. Evans is my favorite of this list.Pikes Peak is nice, but if you want to go on THE highest paved road in North America you should head up the Mt. Evans Scenic Byway, which is only about 50 miles or so from Denver, and closer to your ostensible route through the area. Or better yet, jump off I-70 at US-40 and head over Berthoud Pass, and up and over Trail Ridge Road through Rocky Mountain National Park. The highest paved continuous highway in North America.
