Jeffco Open Space boasts 265+ miles of trail along the Front Range of central Colorado. From concrete trails in suburban parks like Crown Hill in Wheat Ridge that traces the perimeter of Crown Hill Lake, to rough and rocky natural surface trails at Elk Meadow Park in Evergreen that climbs to 9,708 feet to the top of Bergen Peak, and all manners of trail in-between. Our parks have trails to fit varying abilities, experiences, and recreation types.

Regional Trail Connections

Regional trails make critical connections across public lands and ease congestion in parks as they encourage leaving the car at home. Learn more about the following regional trails in Jefferson County that connect to the Jeffco Open Space system: Bear Creek Trail, Clear Creek Trail, Fairmount Trail, North Fork Trail, Peaks to Plains Trail, and Pioneer Trail.

Trail Management

Trail Usability

In a continuing effort to provide equitable access for visitors of varying abilities, JCOS is in the process of auditing Open Space trails to determine where and when "usable trails" can be created. Usable trails provide a prolonged trail experiences for those individuals using mobility devices where ADA requirements cannot be met. Prolonged experiences can be created by simply hardening the trail tread and removing obstacles that might impede mobility devices. 

Trail Assessments

With over 56,000+ acres of managed land, 260+ miles of trail, 27 parks, and high visitation, taking care of existing parks and trails is top priority for Jeffco Open Space. In order to do this job effectively and efficiently, an annual trails assessment was implemented. This assessment helps to develop work plans and priorities for trail maintenance, identify opportunities for volunteer stewardship projects by groups or as a special event, and communicate to visitors where maintenance will be occurring.

Designated Use Trails

The majority of JCOS trails are multi-use and open to hikers, bikers, and equestrians, however there are circumstances where a trail may be designated for a single visitor group to address safety, mitigate visitor conflict, improve visitor experience, or observe topographical conditions.

In addition to trails that are currently designated use, the JCOS 2020-2025 Conservation Greenprint, Goal 9, calls for an additional 21 miles of designated use trails by 2025.

JCOS prioritizes the creation of Designated Use trails: 

  • In new park development
  • With preference for on-going designation over alternating day designation
  • As a priority for parks with relatively high visitor conflict but within the limits of the landscape
  • Not as a given but as one part of a tool kit to respond to the needs of the landscape and visitor use

Prior to designating trails for a specific visitor group, trail alignments go through a review process including: goal establishment, data collection, analysis, identification of alternatives, stakeholder vetting, and community engagement (as appropriate).
