Trail Difficulty Ratings
Use this guide to understand trail difficulty within Jeffco Open Space parks. The ratings mimic ski resort ratings:
Black Diamond = Most Difficult. Trails have steeper grades and greater challenge.
Blue Square = More Difficult. Trails have various grades.
Green Circle = Least Difficult. Trails are less strenuous.
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, Pioneer Trail.
With over 56,000 acres of managed land, 244 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.
Jeffco Trails Plan
Jeffco Open Space is coordinating the creation of the Jeffco Trails Plan, the first countywide trails plan for Jefferson County. The intent of the plan is to create a comprehensive trail system that unites the people, places, and possibilities of Jefferson County. The Plan will assess trail and greenway needs throughout the county and establish priority areas and projects. Implementation of the priority projects will help to improve safety for trail visitors, increase and enhance healthy trail-related recreation opportunities, and allow more people to begin their outdoor experience from their homes. The final plan will serve as a guide for constructing trail improvements over time.
Jefferson County Open Space (JCOS) has completed a draft of the county-wide Jeffco Trails Plan envisioning a healthier, engaged community connected by trails. This draft is a result of a collaborative effort among JCOS, local, state and federal agencies, park and recreation districts, and non-profit partners to identify trail opportunities and implementation strategies that increase safety, access, and connectivity of Jeffco residents to outdoor recreation opportunities. Please review the Draft Jeffco Trails Plan and the Draft Jeffco Trails Plan Implementation Resources documents. Public comments associated with the draft plan can be sent to [email protected] between July 1 - July 30.

Trails Development Handbook
The Trails Development Handbook provides an overview of how recreation trails are proposed, planned, designed, constructed, and cared for in Jefferson County, Colorado. It is especially useful for anyone who would like to propose a new or rerouted trail, or learn more about the trails development process.
Trail Proposal Process
Jeffco Open Space allows for proposals of new trails and has an application process for those that want to submit a proposal. After submittal, a trail proposal application will be assigned an initial priority ranking, which will determine when subsequent evaluation will take place or if the project will be declined at that time. Potential trails that offer the greatest value to Jefferson County residents will be given the highest priority and moved into the Planning step as outlined in the Trails Development Handbook.
