The City of Boulder plans to use a helicopter on Tuesday, Oct. 18, to move materials to help conduct repairs on the Mount Sanitas Trail. City of Boulder Open Space and Mountain Parks anticipates that the helicopter will operate between 6:30 a.m. and 5 p.m. on Tuesday, Oct. 18. If weather conditions are not suitable on Tuesday, helicopter work will occur as soon as weather conditions allow.

The city will close the Mount Sanitas trail and portions of the Sanitas Valley and Dakota Ridge trail while the helicopter operates. The East Ridge and Lion’s Lair Trail will remain open. OSMP encourages community members to visit OSMPTrails.org to view current trail closures across Boulder’s open space system.

Funding for this project is supported by the Boulder Open Space Conservancy (BOSC), City of Boulder Open Space and Mountain Parks’ official nonprofit partner. BOSC’s mission is to promote and enhance the ecological resilience of our public lands to climate change through sponsorship of conservation projects and community education for the benefit of all current and future generations of Boulder citizens and visitors. BOSC is raising funds to support OSMP’s Mount Sanitas Trail repair and natural land restoration efforts. Learn more about BOSC and how you can help support Boulder's open space.

Rangers may issue citations to people who access closed trails/areas. The helicopter cannot complete its work if open space visitors are in the construction area – which may result in safety hazards and costly trail construction delays.
