Climb Summary


Bike climb of Independence Pass - Continental Divide sign and PJAMM cyclist Stacy Topping

Cycling Independence Pass - Route from Aspen is a US 100 Bike Climb.

Ride 15.8 miles gaining 4,128’ to 12,095’ at 4.8% average grade.

Independence Pass is in the Sawatch Range of the Rocky Mountains and White River National Forest (established 1902 by President Teddy Roosevelt; 2,285,970 acres).  Indepence “Pass” is the highest pass in paved actual pass in the US at 12,095’. Mt Evans, Pikes Peak, Mauna Kea are higher but end at the top. Cottonwood Pass is a bit higher, but is not paved on one side.  Trail Ridge is slightly higher, but its high point is not marked as a “pass” (Iceberg Pass is down from the Trail Ridge high point at 11,827’).   Thus, Indepence Pass claims the prize for highest paved pass in the US.

 

From the West (Aspen)

We climbed Independence Pass September 4, 2014 and reached the summit in the snow!

The scenery that I could see along the climb was wonderful and the rock formations were interesting, making this a gorgeous climb.   Photos provided by PJAMM contributors confirms that Independence Pass during good weather is a gorgeous bike climb.

 While the road is a wide highway there is minimal shoulder and  moderate highway traffic with some sheer drop offs over guardrails towards the top - chilling for  someone with height issues such as I.  You will get a very good sense of the climb by viewing our YouTube video.

Independence Pass is the third highest paved pass in Colorado and one of only 6 Top 100 climbs exceeding 12,000' (5 of the 6 are in Colorado).   With traffic conditions (see below), altitude, and cliffs, this climb is an adventure for sure!

Steepest ¼ mile begins at mile 1.9 (8.8%) and steepest mile at 2.8 (6.8%)

Highest paved passes in Colorado, all cross the Continental Divide:

  • Cottonwood Pass, Buena Vista, CO - 12,127
  • Trail Ridge, Estes Park, CO - 12,183’

Roadway surface and traffic:  This is the primary vehicle access to Aspen and does have a  fair amount of traffic.  The roadway is in excellent condition, but the climb is a bit hair raising  with vehicles zipping by (at lower speed due to the narrow road and steep drop offs in  places) very close to you.  We rate this as a mildly treacherous ascent.

From the East

The eastern approach to the pass is less challenging and scenic than from the west, but finishes at the same high altitude as from Aspen, of course!  So the altitude alone makes this one a bit tougher than its pedestrian statistics suggest.

 

Steepest ½ mile begins at mile 12 (6.7%)
