Published on August 26, 2026

A portion of the Meadowlark Trail at Coalton Trailhead will temporarily close on Monday, Sept. 7, for cattle grazing. The closed section starts at the Coalton Trailhead (3495 McCaslin Blvd.) and runs north toward the Oerman-Roche Trailhead, highlighted in red on the map below. Trail users can access the crusher fine trail on the east side of McCaslin Boulevard to get between the Coalton Trailhead and the Oerman-Roche Trailhead. Coalton Trail and all other trails remain open during this time. This section of the Meadowlark Trail will remain closed through Saturday, Nov. 7. Visit Boulder County's website for more information, including an instructional video demonstrating how to use the detour.

Here's how the detour works:

1. Go east through the roundabout at Coalton Road.
2. Go north along the trails and sidewalks that are physically separated from McCaslin Boulevard.
3. Go west across McCaslin Boulevard at the crosswalk at Rock Creek Parkway.
4. Go north on the trail along the west side of McCaslin Boulevard to the Oerman-Roche Trailhead.

Please remain aware and use caution at the crosswalks.

Boulder County manages cattle grazing, which plays a key role in reducing wildfire risk, maintaining healthy grasslands, and improving soil health. The trail will be closed during grazing out of an abundance of caution, as cattle in this area have previously been protective of their young and aggressive toward trail users.

We appreciate your understanding as we work to balance trail access with important land management efforts!
