Muddy trail closures as of Friday, March 23, 2018
The Left Hand Trail from Boulder Valley Ranch to Neva Rd is now open. Trails in the Marshall Mesa, Greenbelt Plateau, Flatirons Vista, Doudy Draw and Springbrook areas are closed because of muddy conditions. Marshall Mesa, Greenbelt Plateau and Flatirons Vista Trailheads are closed. Doudy Draw Trailhead remains open to allow vehicle parking for visitors accessing the South Mesa area, but trails leading south out of Doudy Draw Trailhead are closed. OSMP staff will monitor trails and open them when conditions dry out.

Red Rocks and Anemone Trails temporarily closed
As a continuation of a critical water line replacement project the Anemone Trail and sections of the Red Rocks Trail are expected to be closed until March 23, 2018 when the department anticipates completing the project. This closure affects individuals heading north from the Settlers Park Trailhead or south from Centennial Trailhead. Open Space and Mountain Parks is working closely with Public Works to minimize the needed closure time so check back frequently. OSMP expects to be able to open sections of the closure, including Anemone, over weekends. Please check back frequently for updates. View a map of the closure area.

Foothills South Trail closed beginning March 7, 2018
The Foothills South Trail is closed from the Utica Ave. access to Four Mile Canyon Creek for a flood repair project. Closures will occur from 7 am to 5 pm, Monday through Friday, and the project is estimated to take approximately two months to complete. More information is available at

Boulder Falls Trail remains closed
Starting as early as  Monday, Feb. 12,  OSMP will begin work to repair Boulder Falls. During this repair project, OSMP will rebuild gabion walls – which are rock baskets used to catch sediment coming off the hillside – and conduct repairs to stabilize the trail. The project also will improve trail tread. Boulder Falls remains closed.  Because of equipment needed to conduct these repairs, there will be no parking available at Boulder Falls pull offs along Boulder Canyon.

East-Boulder White Rocks Trail section closed
The bridge on the East Boulder-White Rocks Trail is closed after flooding conditions on the path caused the bridge to become disconnected from its embankment. OSMP advises visitors not to approach the bridge. The East-Boulder White Rocks Trail remains open up to the bridge closure from both directions, but no through trail travel is allowed - see the closure map

Flagstaff Summit Road closed to vehicles for winter Oct. 31, 2017
The Flagstaff Summit Road is closed to vehicles for the winter. It will reopen to vehicles May 1, 2018.

Rock Island 1 in Boulder Canyon closed
Rock Island 1 is closed. The rock fractured and part fell onto the Boulder Canyon Creek path. Sections of the remaining rock have been evaluated as unstable so it is closed until recommended bolting can be completed.   

No parking along Highway 170 near Doudy Draw and South Mesa Trailheads
Please remember that parking is not allowed on Highway 170 at any time.
