Recreation Opportunities
The county has a rich heritage of outdoor recreation and trail use. The county’s immense scenic beauty and mix of geography, public lands, and tourism combine to create world-class recreational amenities and opportunities. By and large, recreation remains the most important aspect to a vital Summit County economy.

Summit County Open Space and Trails works with multiple partners including the partners U.S. Forest Service and our local towns. Our properties are often gateways to the vast recreational resources that the USFS provides. We have numerous trail portals and parking areas throughout the county, providing a variety of recreational opportunities.

The State of the Open Space Report summarizes Summit County's open space program’s accomplishments since its 1996 inception. The report presents the current open space system and the many trails owned and managed by the County. It also provides clear metrics to measure the progress of the County's program, including miles of trails, acreage of protected lands, and acquisition-related expenses.

  • We have protected close to 16,000 acres of land as open space.
  • Each tax dollar spent to date to purchase open space has protected over $3 worth of property in Summit County, because our funds leverage contributions from property owners, the Colorado Lottery and other organizations.
