Other Trail Closures and Advisories
Doudy Draw Trailhead closure Nov. 28 - Dec. 14, 2022
The trailhead will be closed from Monday, Nov. 28 to Wednesday, Dec. 14 while contractors redesign and re-grade the parking lot within the existing footprint. This includes re-orienting the horse trailer and vehicle parking and relocating the driveway entrance to allow for better circulation and a safer, more functional trailhead. The trailhead will not be accessible to the public during this closure, but access to the trails will be provided via a temporary detour off the South Mesa/Doudy Draw connector trail. Please note this temporary access trail is not established and may cross uneven terrain.
Boulder Star Area Closure

Marshall Fire-related trail restrictions
On-trail-use-only regulations in the Marshall Mesa area continue to be enforced as the area has changed since the Marshall Fire and hazards may be present. Some properties affected by the Marshall Fire remain closed while staff monitor ongoing ecological and agricultural needs on those properties.
Creek Closures to Limit Spread of Invasive Mudsnails Instituted
The City of Boulder has closed access to South Boulder Creek at the South Mesa Trailhead to prevent the spread of a highly invasive aquatic species, New Zealand Mudsnails (NZMS). The South Mesa Trailhead and the Mesa Trail will remain open. Learn more about the NZMS closures.
