The number of people climbing a 14,000-foot peak in Colorado last year fell by 27 percent to
303,000 hiker use days, according to the most recent
hiking use report by the Colorado Fourteeners
Initiative (CFI). Access and parking restrictions at several of the state’s most popular 14ers near the Front Range
saw an even higher drop. Included was a 65% decline in estimated climbing use in the Mosquito Range that
includes the popular Decalibron Loop (Mounts Democrat, Cameron, Lincoln and Bross bypass) that was closed by
the private landowner between May 1 and August 6. The statewide economic impact of hiking Colorado 14ers in
2021 was $82.2 million based on past 14er hiking use expenditure studies.
“The pandemic boom in 2020 was followed by a significant bust in 2021, as trailhead communities looked
to control parking, landowners closed access due to liability concerns, other recreational options opened up as the
pandemic lessened, and wildfire smoke choked off visitation mid-summer,” said Lloyd F. Athearn, executive
director of CFI. “More than half of 14ers in the ranges closest to Front Range population centers faced some sort of
access restriction. This contributed to the largest drop in 14er hiking use statewide, an estimated 69,000 hiker use
days. However, use fell the least in the Sawatch Range (-13%), suggesting that people unable to climb on closer
ranges drove farther to climb 14ers that were not affected by restrictions.”
Despite parking restrictions at the main trailhead starting on July 30,
Quandary Peak remained the most
climbed 14er in Colorado in 2021, with an estimated 35,000 to 40,000 hiking use days (best guess = 35,000 days).
Use on Quandary dropped 29% from an estimated 45,000 to 50,000 days in 2020. Mount Bierstadt, which faced no
access restrictions, again took second place with an estimated 30,000 to 35,000 days (best guess = 32,000 days).
This was down from an estimated 35,000-40,000 in 2020. The Grays and Torreys Peaks combined route tied for
third place with Mount Elbert in a range of 20,000 to 25,000 use days (best guess for both routes = 22,000 days).
Clear Creek County posted “no parking” signs along the Stevens Gulch Road to Grays/Torreys last year and cited
violators. This forced many people to park near I-70 and hike the 3.5-mile-long road, contributing to lower use
levels. The Grays/Torreys route in 2020 saw 30,000 to 35,000 estimated hiker days. Parking in 2021 for the primary
Mount Elbert route was located a mile farther from the trailhead due to road construction, contributing to a longer
climb. Elbert use in 2020 was in the 20,000 to 25,000 days range. Pikes Peak rose to fifth place in 2021 with an
estimated 10,000 to 15,000 hiker days. This was down from 15,000 to 20,000 days in 2020.
The route showing the greatest decline in hiking use statewide was the “Decalibron Loop” that
encompasses Mounts Democrat, Lincoln and Bross. The route was closed from May 1 through August 6 due to
landowner liability concerns. (Note: The actual summit of Bross remains closed due to private land issues, but
hikers are permitted on a bypass loop route near the summit). The route was the fourth most-popular in 2020
(estimated use of 25,000 to 30,000 hiker days) but fell to an estimated 7,000 to 10,000 days last year. Climbers
largely complied with the closure, but use levels did not return to 2020 levels even after the August reopening.
Estimated use in 2021 on nearby Mount Sherman was cut roughly in half compared to 2020.
Access to Mount Lindsey in the southern Sangre de Cristo Range was also closed due to landowner
liability concerns. Use levels did not decline appreciably due to the closure since it came at the end of the season
when use levels are normally low.
Smoke from more than 100 western wildfires was a further limit on hiking use in parts of the 2021 14er
hiking season. Counters statewide showed a plunge in hiking use the first full weekend in August when air quality
reached unhealthful levels. Media reports said that Denver’s air quality for several hours on Saturday, August 7
was the worst of any city in the world.
Colorado was the fourth-fastest-growing state between 2010 and 2019, growing its population by 14.5
percent. The Denver metro area has grown nearly 15 percent during the same period. In-migration was highest for
those aged 24-32, the prime age for fit, outdoor-oriented people to be exploring Colorado’s high peaks.
CFI’s estimate of hiking use suggests a statewide economic impact of almost $82.2 million directly
attributable to hiking 14ers based on economic expenditure studies performed by Colorado State University
economists John Loomis and Catherine Keske. Their 2009 study found that climbers of Quandary Peak near
Breckenridge spent an average of $271.17 per day for gasoline, food, lodging, equipment and other retail
purchases. This expenditure estimate has not been updated in almost a decade, so it is likely understated.
CFI’s hiking use projections are based on the combination of several data sources. 1) CFI collected hourby-hour data during the 2021 hiking season using compact infrared trail counters that were placed at 23 locations adjacent to summit hiking trails servicing 21 14er peaks. Hiking use is estimated for the period between May 25 and October 11. Missing data were modeled using a linear model incorporating week number, day of the week,
holiday and use levels on other similar peaks, which has shown to be statistically accurate. 2) Hiking use
projections for all other 14ers were based on crowdsourced “14er checklists” submitted to the 14ers.com website
by more than 21,400 individual hikers. Estimates for peaks without trail counters were determined using a trend
line calculated by the relative frequency of reported hiking use on all peaks using data points as anchors for peaks
that had trail counters in 2021.
CFI began deploying compact infrared trail counters as part of a pilot program in 2014 at five locations:
Grays/Torreys, Castle, Quandary, Redcloud/Sunshine and Handies Peaks (American Basin). The program was
expanded in 2015 to five additional locations: Mounts Elbert (3 locations), Democrat and Handies Peak (Grizzly
Gulch). Additional funding in 2016 allowed CFI to add 10 new monitoring locations: Mounts Sneffels, Sherman,
Princeton, Antero and Shavano, La Plata,
Huron and Wilson Peaks, Challenger Point/Kit Carson Peak and Blanca
Peak/Ellingwood Point. In 2017 the Antero counter was moved to the Winfield approach to La Plata Peak. In 2018
two new counters were deployed on Pikes Peak (Barr Trail and Devil’s Playground), while the La Plata (Winfield)
counter was moved to the West Ridge of Quandary and the Princeton counter was moved to Mount Lindsey. In
2020 the West Ridge of Quandary counter was moved to a new, better location on Mount Princeton, while a new
counter was deployed to Mount Bierstadt. Hiking use is being monitored at 22 locations during the 2022
summer/fall hiking season after theft of the Bierstadt counter.
CFI uses the term “hiker use days” to report hiking use on the 14ers. This represents one person hiking
one peak on one day. Anecdotally we know that individual enthusiasts may hike multiple 14ers over the course of
a given year, including climbing the same peak multiple times. Using “hiker use days” reports the number of days
of hiking use that occurred but does not represent the number of individual people who hiked 14ers that year.
