Cottonwood Pass

Cottonwood Pass, a sensational road in Colorado

Cottonwood Pass is a high mountain pass at an elevation of 3.696m (12,126ft) above the sea level, located in the Rocky Mountains of south-central Colorado, in Chaffee County, United States. It's one of the highest mountain roads of Colorado.

Is Cottonwood Pass in Colorado paved?

The road to reach the summit, from Buena Vista to the east, is called Chaffee County Road 306, but near the summit the road name changes to Gunnison County Road 209 as it continues to the west. The drive is a great one to take in the fall to enjoy the changing colors before the snow comes. After long-term closures (3 years) and heavy construction, the road to the summit was fully paved the entire way from Buena Vista to Taylor Park Reservoir (and to Crested Butte and/or Gunnison) on 2019. The newly paved west side is wide and smooth, no problem for any type of vehicle. As before, the road won’t be plowed in the winter. Additional improvements to come include two 11-foot travel lanes with shoulders, guardrails, protection from rockfall, and additional parking areas at the summit and Denny Creek. It’s said to be one of paved passes in America. The idea for the Cottonwood Pass road began in 1955 when the Forest Service needed a way to get timber out. By 1958 there was a road – but it was dirt.

Is Cottonwood Pass open in Colorado?

The pass tops out over 12,000 feet, has the third highest paved road in the state, has an incredible tree lined climb on the east side with a 10% grades section. It has switchbacks, scenery, and very little traffic. It’s a great shortcut between Buena Vista and Crested Butte and is a great alternative to Monarch Pass a few miles to the south. Gorgeous Cottonwood Pass winds its way up and over the mountains between Buena Vista and Crested Butte, providing a beautiful scenic drive. In July 2002, heavy rains from a thunderstorm east of Cottonwood Pass caused a significant mudslide that blocked portions of Chaffee County Road 306 for many days. Note that there are seasonal gates at both ends and the trail is closed during the winter. The pass is closed seasonally due to heavy snowfall, typically from around October until sometime in May. Conditions can change quickly and be harsh. When open, the pass is one of the few routes through the Sawatch Range accessible in a standard two-wheel drive passenger vehicle. 

How long is Cottonwood Pass?

Starting from the Town of Buena Vista in Chaffee County, heading over the Continental Divide, the drive is 19.3 miles long via State Hwy 306. Allow 33 minutes to drive. There is a nice parking area at the top with expansive views to both the east and west sides of the Continental Divide. It is well worth the trip. Cottonwood Pass is a route that can be used to travel from Buena Vista to Crested Butte. Thunderstorms often develop in the afternoon in the Colorado high country. Visiting early and being back by your vehicle early in the day is advisable. Be aware of high altitude sickness, which can be life threatening. Hypothermia can be a hazard throughout the year. There are a few switchbacks near the top, but the road gets wider and easier as you get lower in elevation. There are a few overlooks on the way down from the pass that are definitely worth the stop. Given that the pass is over 12,000, it’s likely you will find snow at the summit year round. But more than that, this is a pass where the weather will change rapidly and any attempt to ride the pass should be done with due care. Have a lot of water with you and have foul weather gear. The ride is rather remote and you won’t see too many other people if you need help.
