Trail and Area Closures and Advisories
Open Space and Mountain Parks (OSMP) makes every attempt to keep this page as up to date as possible. However, some closures and trail advisories are made on an emergency basis for the safety and well-being of our visitors, wildlife and natural resources. Please watch for these signs during your visit. Descriptions of closures and links to more information, including maps, are below.
COVID19 closures and cancellations: The OSMP Hub at 2520 55th Street and the Chautauqua Ranger Cottage are both closed, as are picnic tables, shelters and facilities.
