Mountain towns and state parks along the Front Range are preparing for one of the busiest seasons of the year, when leaf-peepers arrive to bask in the glory of golden aspen trees. While there’s plenty to romanticize about this fall tradition, overcrowding has become common in scenic areas and forced local governments to adapt in how they manage traffic congestion.
Breckenridge, for example, will close the Wakefield trailhead to cars for the first time this season and require visitors to take a free shuttle to the popular Aspen Alley trail. Officials in Park County and Clear Creek County, on both sides of Guanella Pass, are prepared to issue tickets and tow cars when they find people parking illegally.
“We obviously have had issues in the past with leaf peeping season up on Guanella Pass with traffic enforcement largely due to people parking illegally or double parking, taking up the roadway,” said Park County spokesperson Jo Keats. “We had an incident a couple of years ago where our emergency services personnel were significantly delayed in reaching people who needed help because of this issue.”
Last year, the counties worked with the U.S. Forest Service and the Colorado Department of Transportation to install temporary “no parking” signs along the pass to keep traffic moving. They also put up electronic signage alerting drivers about towing enforcement and increased the number of deputies monitoring the area.
Both strategies seemed to deter illegal activity and will be in place again this fall, said Jenny Fulton, spokesperson for the Clear Creek County Sheriff’s Office, which issued 127 parking tickets during the 2025 leaf-peeping season. Keats estimates Park County towed 12 cars. Both figures represent just a fraction of the 25,000 to 30,000 vehicles that typically travel Guanella Pass each week during the height of fall, Fulton said.
Guanella Pass parking restrictions go into effect on Sept. 11, earlier than usual, as drought is expected to cause the leaves to change ahead of schedule this year.
Golden Gate Canyon State Park, a well-known leaf-peeping destination northwest of Golden, will also have more staff patrolling the grounds to enforce parking restrictions and potentially write tickets. In recent years, the park has installed ropes and poles to designate parking spots on unpaved lots and posted more "no parking" signs along the road to prevent people from parking where they are not supposed to. That happens commonly during the fall; one park manager characterized the boom in visitors by saying “we literally get run over” in 2023, The Denver Post previously reported.
Golden Gate only has 400 parking spots to accommodate daily visitors, but demand far outpaces its capacity. Last year, it saw 492,287 people come through the gates during September and October, according to Colorado Parks and Wildlife visitation data.
“The etiquette is that while you drive by a parking lot and a space is available or someone is pulling out, you can grab it. However, if the lot is full, you need to keep driving to the next lot,” CPW spokesperson Bridget O’Rourke said by email. “You can't just stay on the road and block traffic, because park rangers will wave you on.”
Tips for avoiding traffic congestion and crowds
If you don’t want to fight leaf-peeping crowds for a parking spot, O’Rourke suggests visiting Golden Gate Canyon and other state parks on weekdays when they are much less crowded. Be aware, the Colorado Department of Transportation will also be doing through the park to resurface the road.
Traffic on Guanella Pass also decreases significantly Monday through Thursday compared to weekends, Fulton said. On Saturdays and Sundays from 1 to 4 p.m., as many as 10,000 vehicles often travel the pass. In 2025, the sheriff’s office closed the I-70 exit to Georgetown, the gateway to Guanella Pass, at least once because of traffic backing up in town.
In any case, Fulton advises having a backup plan to either leaf-peep elsewhere or spend a couple hours in Georgetown until traffic dies down.
Locals can avoid driving altogether by taking the Bustang, which offers several different routes into the mountains, including and another with stops in Idaho Springs, Frisco, Vail, Avon, Eagle and more. The Bustang Outrider also provides service to , , Steamboat Springs, Granby, and Winter Park from Denver.
