Special Activity

Applications for Special Activities are accepted and reviewed once per year and the application for 2021 events is now open through October 8th, 2020 at 11:59pm. Applications will be reviewed and applicants notified no later than December 1st, 2020.  

Events such as tours, races, rides, walks, festivals, fun runs, etc. require a special activity permit and will fall into one of two categories:

Category 1 - Events that exceed 200 people and/or require exclusive use of JCOS managed trails or park. A maximum of five total Category 1 special events may be permitted per calendar year and are limited to a maximum of one event per visitor group: hiking/running, equestrian, mountain biking, the arts, etc. Category 1 events must be administered by a public or non-profit organization to benefit a charitable cause and the organization must be the applicant for the permit. Category 1 events are limited to a single park and maximum of 8 hours.

Category 2
- Events that are 200 or fewer people in total (including staff) and do not require exclusive use of a park, trail or other area.

All events will be considered on a case-by-case basis and those that align with or support the mission of JCOS will be given preference. Further, in recent years JCOS parks have seen a significant increase in visitation with estimated annual visits totaling approximately 6.9 million. This volume of visitation places a challenge on trails, facilities, parking areas, and the experience of other visitors. Applications that take this into consideration and demonstrate measures to minimize impacts on trails, park facilities, parking areas, and park visitors will be given preference. All events should plan to stage all non-trail related activities, including parking, off-site and explain this plan in their application. 

Restricted Dates:

Events that fall on holidays or holiday weekends will not be considered. In addition, JCOS may limit the number and timing of events in certain locations to reduce the impact and inconvenience for park visitors, neighbors and park and natural resources. Currently, the following dates will not be considered for Special Activities in 2020 (please note that this list is subject to change):

January 1 

January 16 to January 18

All approved applications are subject to a cost recovery fee of $5.00 per participant plus 150% of direct cost to JCOS, as applicable, due within 10 business days of the events conclusion. Exceptions and reductions may be made on a case-by-case basis for governmental and non-profit organizations that directly benefit the people of Jefferson County. Justification for an exception or reduction should be reflected in your application. Additionally, all events require a damage deposit which is due no later than thirty days prior to the event.
