Starting at Bergen Park (exit 252 from I-70), Squaw Pass Road rises steadily for about 18 miles up to Echo Lake. From there you'll have the option to ride up Mount Evans Road (closed from early fall to early summer) to the parking lot at 14,130 feet—just 134 feet below the summit. The grade is steady; if you're adequately hydrated through the ride, this climb will seem challenging but doable.
This is a classic moderate-to-high altitude road. In the fall, you'll likely see golden aspens (and snow or slush in shaded corners later on). The best bet is to ride this road on a sunny day in the late morning, then take a break at Echo Lake around noon (where there's a restroom and a phenomenal view). When you turn back, the mid-day sun will have melted the tricky corners in advance of your descent.
The ride down is a blast. It's a wide-open descent with only a few switchbacks (and even those are relatively sweeping). Be sure to bring a wind vest, gloves, and arm and leg warmers for the return trip.
