SUMMARY: To protect natural resources and provide for public safety, the U.S. Forest Service has issued a temporary closure and prohibition order affecting portions of the San Gabriel Mountains National Monument, including the Mt. Baldy Closure Area.
This Order is effective from December 29, 2025, at 10:00 p.m. until December 31, 2025, at 11:59 p.m.

“The tragic loss of life on Mt. Baldy and repeated rescue responses highlight how dangerous current conditions are, even for experienced hikers. Weather and terrain conditions remain extremely dangerous and unpredictable, posing a significant risk to both the public and Search and Rescue personnel. The temporary closure of Mt. Baldy trails is necessary to prevent additional emergencies and protect lives. The public is urged to respect the closure and avoid the area until it is safe to reopen.” Sheriff Shannon Dicus
Members of the public are required to comply with all posted closure signs and directions from Forest Service personnel. These temporary restrictions are necessary to reduce risk to visitors and to protect sensitive natural and cultural resources. A violation of these prohibitions is punishable by a fine of not more than $5,000 for an individual or $10,000 for an organization, or imprisonment for not more than six months, or both.
The San Bernardino County Sheriff’s Department advises all subjects to refrain from traveling to or recreating in the Mt. Baldy area for the duration of the closure. Public cooperation is essential to ensure the safety of visitors and rescue personnel and to support ongoing public safety operations.
