1st/2nd Flatiron Trail project and closures beginning June 4, 2018 
Repair efforts on the 1st/ 2nd Flatiron Trail will continue this year. Work will include the ‘repair in-place’ of numerous failing stone structures and the restoration of eroding slopes. The trail will be closed Mondays through Thursdays from 8:00am-4:30pm. The closure will begin at the base of the 1st Flatiron and will allow climbers to ascend the 1st and then hike back down the trail – delays should be expected. 

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

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.
