I lived there for 13 years.
Take I-25 North to I-470 West to I-70 West and straight to Vail.
I just got back from Cheyenne Mnt State Park last Friday. I was parked in site # 2 and site #16 for a week. The Park is all new (totally funded by Lottery money) and very nice.
An excellent alternate route is to take Highway 24 up through Woodland Park CO. to 9 North at Hartsel town... Easy drive,,, excellent road to Breckenridge to I-70 to Vail.
