September 2026 · Denver and the Colorado Front Range
Colorado mountain road

Hi {{contact.first_name}}, September is the best month to ride in Colorado, full stop. The summer heat breaks, the crowds thin, and the aspens start turning gold across the high country. It is also when the weather gets moody up top, the elk start moving, and a warm morning in Denver can be snow by the time you top a pass. Time it right and you get the ride of the year. Get careless and the mountains will remind you who is in charge.

Ride of the Month: The Peak to Peak Highway

CO-119, CO-72, CO-7 · Black Hawk to Estes Park · ~55 miles of gold

Colorado's oldest scenic byway at the peak of aspen season

Climb out of the foothills to Black Hawk and pick up the Peak to Peak Highway north, stitching together CO-119, CO-72, and CO-7 through Nederland, Ward, and Allenspark up to Estes Park. In late September this is the aspen show, whole mountainsides going gold with the snow-dusted peaks of the Indian Peaks and Longs Peak standing over it. It is one of the finest fall rides in the country and it is right in Denver's backyard.

Start early, dress in layers because it will be cold at 9,000 feet, and give yourself time for the leaf-peeping traffic that stacks up on the weekends. Fuel up before you climb, watch for gravel in the shaded corners, and take it home down Boulder Canyon or Coal Creek before the afternoon weather builds.

Also worth the ride

For a shorter loop, run the Lariat Loop up Lookout Mountain out of Golden, some of the tightest, prettiest switchbacks near the city with the whole Front Range laid out below. Want to earn a summit? Guanella Pass out of Georgetown climbs to nearly 12,000 feet through prime aspen country. Both are cold and weather-exposed up top, so watch the sky and carry a layer.

Early-Fall Safety: Colorado Edition

September in the high country is beautiful and unforgiving. The mountains bring a whole different set of hazards.

Know Your Colorado Law

  • Fault gets split, and there is a cutoff. Colorado uses modified comparative negligence. Your recovery drops by your share of the blame, and if you are found 50 percent or more at fault, you collect nothing. How the crash gets documented decides the number.
  • The minimums are low, so lean on UM/UIM. Colorado requires only 25/50/15 in liability, which does not go far after a serious motorcycle wreck. Uninsured and underinsured motorist coverage is your real backstop when the driver who hit you carries the bare minimum or nothing.
  • Helmets are optional for adults. Colorado requires a helmet only for riders and passengers under 18. Riders 18 and older can ride without one, though eye protection is required. A helmet is still the best call every single time.
  • You have three years. Colorado gives you three years from the date of a motor-vehicle crash to file an injury claim, longer than most states. Evidence still fades fast, so do not wait to get advice.
