Boulder’s Bike Ban
The story of the country’s longest standing bike ban.
Boulder’s Bike Ban
The City of Boulder has the dubious distinction of the country’s longest standing bike ban on singletrack trails in public open space. Few now remember the early days of klunkers when locals took their new-fangled off-road bikes on the Mesa Trail. That ended when Boulder prohibited bicycling in the area around the Flatirons in 1983. City Council reconfirmed and expanded the ban in 1987. To this day, bikes are not allowed on any of the 70 miles of trails between Eldorado Springs and Wonderland Lake.
The reasons given for the closure were the scientifically refuted claim that bikes cause more resource damage than hikers1 and worries of user conflict. “Hikers and other naturalists argued that the bikes erode trails, disrupt the tranquil setting of a nature trail and pose a danger to hikers” (1983)2 and “…it is the purpose of the open space trustees to protect and preserve our natural environment.” (1987)3
In 1998 the Boulder Mountain Parks & Open Space’s (OSMP) department began a planning process that created some hope that the bike ban could be overturned or at least modified. The seven-year planning process resulted in the 2005 Visitor Master Plan which divided Open Space into regional sections (Trail Study Areas (TSA)) for evaluation. The 2005 Marshall Mesa/Southern Grasslands TSA and the 2006 Eldorado Mountain/Doudy Draw TSA went well for mountain bikers. The existing Doudy Draw trail was reopened to bikes and the plans called for the creation of the new singletrack trails Crowdy Draw, Coal Seam, High Plains, Springbrook, Flatiron Vista and Prairie Vista to be open to bikes as well.
In 2008, the first whispers of a re-evaluation of the western Open Space lands began, with the public process starting in earnest in 2010 to plan the West Trails Study Area (West TSA). The success of the first two TSAs gave BMA the hope that there would be some bike access reopened in the west by the Flatirons as well. OSMP formed a citizen advisory group called the Community Collaborative Group (CCG) to give stakeholders and neighborhoods a voice in the process. OSMP mandated consensus as the decision-making process so just one dissenting vote could end any decision. BMA’s aspirations were of a north-south singletrack connection starting at Baseline Rd. and ending at Doudy Draw. A second, shorter option would be a connection between Shanahan Ridge and Doudy Draw.
A neighborhood group calling themselves Save Open Space Boulder (SOS Boulder) came out vehemently opposed to any bike access, claiming “mountain bikes would pose safety risks to other trail users and that they would fundamentally change the open space experience,”4 any new multi-use trails would irreparably fragment habitat, as well as add parking congestion to the streets. CCG could not come to a consensus on any mountain bike access. Ultimately Boulder City Council voted on March 3, 2011 to uphold the bike ban by a narrow 5-4 majority.
At that March 3, 2011 meeting, City Council requested that OSMP staff evaluate Anemone Hill as a possible multi-use loop or connection to Boulder Canyon and Betasso Preserve. Staff studied these options during the summer and they and the Open Space Board of Trustees recommended a connection be open to bikes, but that route never was deemed viable. Boulder City Council again voted against bike access on November 8, 2011.
The only concessions given were the gravel fire road Chapman Drive and a promise to advocate for the Eldo to Walker multi-use connection – which relied on the cooperation of both the state park and Boulder County. OSMP opened Chapman Drive to bike use in 2013. The Eldo to Walker connection was unilaterally killed by Colorado Parks & Wildlife in 2021.
And where does that leave us today? The city of Boulder does not have plans to revisit the West TSA. Even now, staff is still working on action items from that decision, like the new Anemone Hill hiking trail that partially opened in fall 2021 and won’t fully open until 2022. Additionally, OSMP has yet to start building the North Sky trail or the Boulder Valley Ranch redesign outlined in the 2016 North TSA decision.
So will the Boulder Flatiron bike ban ever be overturned? Answer: not any time soon. Has BMA given up? Answer: heck no!
CITY OF BOULDER BANS MOUNTAIN BIKES FROM OPEN SPACE
City Council decides bikes do not belong in Open Space. The reasons given for the closure are the scientifically refuted claim that bikes cause more resource damage than hikers and worries of user conflict. “Hikers and other naturalists argued that the bikes erode trails, disrupt the tranquil setting of a nature trail and pose a danger to hikers.”

On February 19, bikes are banned from all trails until the Open Space Board of Trustees and the Parks and Recreation Advisory board reopen selected trails.

In the summer of 1983, Boulder reopens selected trails to mountain biking, about a third of the total mileage.
LIMITED MOUNTAIN BIKE ACCESS PERMITTED
The Mesa Trail is closed to bikes from NCAR to Chautauqua but some mountain bikers ignore the rule.

Few singletrack trails are open to bikes – just the Bluebird Shelter/Enchanted Mesa Loop, the Tenderfoot Loop, and trails south of NCAR. Local bike shop owners encourage trail etiquette and Bicycling Magazine portends, “The tug of war between fat-tire bike riders and environmentalists has just begun.“

BOULDER UPHOLDS BIKE BAN
City Council bans bikes from the Bluebird Road/Enchanted Mesa Loop and the Tenderfoot Loop. “In 1986 alone, city park rangers fielded 102 complaints about mountain bicyclists – a 500 percent increase from 1985 – observed 136 cyclists in off-limits areas and issued 24 summonses and 256 warnings.” Mention of newly formed Boulder Mountain Bike Coalition. Officials argue that having any trail open to bikes leads to confusion and noncompliance.

BOULDER OFFROAD ALLIANCE FORMS
In 1991 a dedicated group of riders get together to form the Boulder Offroad Alliance (BOA) to start working to roll back the ban and expand riding opportunities. Galvanized by the death of Sugarloaf resident Sherrill Amendt, BOA’s mission is made all too real. Sherrill is killed on September 3, 1991 by a motorist while riding on Boulder Canyon Drive during a period when the Canyon Trail is closed and gated due to private property issues.
BOA changes its name to the Boulder Mountainbike Alliance in 2006 to avoid confusion with motorized sports.

BOULDER APPROVES THE VISITOR MASTER PLAN (VMP) FOR OPEN SPACE
BMA works closely with BATCO on comments and suggestions for the VMP.

The VMP’s purpose is to provide a framework for decisions that will ensure a continued high quality visitor experience, while at the same time ensuring that the lands are protected and preserved for future generations. The plan calls for evaluating open space in a piecemeal fashion with the land from Eldorado Springs to Wonderland Lake as one chunk.

OSMP BEGINS THE WEST TSA AND SELECTS VOLUNTEERS FOR THE COMMUNITY COLLABORATIVE GROUP
OSMP contracts with Peak Facilitation Group to lead a citizen advisory group called the Community Collaborative Group (CCG) in September 2009. The 15 volunteers are selected through a caucus process and approved by OSBT. OSMP mandates consensus as the decision-making process. Mountain bikers are accused of trying to take over the process when rider Kevin Knight, then a professional conservation ecologist with the Environmental Defense Fund, tries to gain a seat with the conservation group. Mark McIntyre is chosen to represent the mountain biking group.

Boulder votes to buy parcels and work with a private land trust to open Chapman Drive to bikes. Despite this existing corridor open to emergency vehicles, it still takes a public process to open to bikes. The trail opens in January 2013 but it isn’t until June 2013 that bikes are allowed downhill travel. BMA is disappointed that this isn’t a singletrack trail but hopes that it could one day become part of a longer, off-road regional trail connection.

THE ELDO TO WALKER MULTI-USE CONNECTOR TRAIL
The last recommendation of the West TSA is the long anticipated Eldo to Walker Trail. Staff begins a feasibility study in 2013 and the public process kicks off in August 2018. After 6 contentious months, staff puts the Eldo to Walker Trail Connector Public Process on hold while Colorado Parks and Wildlife (CPW) conducts a Visitor Use Management Study for Eldorado Canyon State Park.
In April 2021 CPW announces that they “will not be adding the multi-use connection to the Eldo-Walker trail. Park operations cannot support building and maintaining a new segment of trail or increasing visitation for another recreational use causing exacerbated safety concerns on the congested park road.“
