News & Events
PLAN Jeffco has been a key part of Jefferson County’s Open Space history since 1972. As an all volunteer group we are dedicated to preserving the legacy of Open Space in our county.
Parks & Trails
Jefferson County Open Space has protected more than 56,000 acres of land, while creating 27 regional parks and about 261 miles of trails that can be enjoyed without entry fees.
One of the best ways for us to celebrate these achievements and remind ourselves of the importance of continued support of these values is to simply visit and enjoy one of our many Open Space parks.
Featured Parks
Mount Falcon Park
Hikers at Mount Falcon Park have 1.7-mile Turkey Trot Trail all to themselves. The remaining 11 park miles are multi-use.
Lair o' the Bear Park
Lair o’ the Bear Park is a favorite of Open Space visitors and families due to its abundance of picnic tables and charcoal grills and proximity to Bear Creek for fishing.
