At least some of these scenic byways (such as the Peak to Peak Scenic and Historic Byway - listed in TA as "Peak to Peak Scenic Highway" under Estes Park) have their own individual listings in TA.
I have driven several of these roads, the last time being in September. I probably should get out the camera and visit more of them. Most are interesting at virtually any time of the year.
It's definitely worth visiting the official Website on these roads (linked to on the masthead of this TA review page as of this writing), and trying to fit one or more into your visit.
