Personally, I would recommend going south from Estes on CO 72/119/US 6 to meet I-70 just east of Idaho Springs. That way you avoid both Trail Ridge and Denver.
To get to CO 72, leave Estes Park on CO7. It's a bit of a climb out of the Estes Valley, but there are some beautiful views. The roadway is narrow and in poor condition from Estes Park to near the Larimer/Boulder County line, so take it easy. The intersection of CO7 and CO72 is south of Allenspark; watch for the signage. Make a right and enjoy the drive.
