Trails covered in my hiking guidebooks may be closed for a variety of reasons, with wildfires being the most common. For each trail closure I list the hike name, hike number, and book name.
I also list trails that have had major recent changes, usually meaning a wildfire burned through the area, although the trail is still open.
Note: I try my best to keep this list up to date, but you should always double-check with the relevant government agency for the latest information. Also be aware that this list only covers the trails in my books, not the many other Northern California trails that may also be closed.
Note also: this list does not address trails and trailheads that are inaccessible due to snow, short-term weather events, or short-term wildfire fighting. I do my best to stay on top of trail closures due to larger wildfires.

In early July of 2021, Mud Creek on the north side of Mount Shasta flooded Pilgrim Creek Road and covered it with mud and other debris. This affects:
Clear Creek Trail on Mount Shasta, Hike 46, Day Hiking: Mount Shasta, Lassen & Trinity Alps Regions.
Here’s the most relevant Facebook post (July 12) from the Shasta-Trinity National Forest page:
Mud Creek, on the Shasta McCloud Management Unit, is continuing to have significant surges with the high temperatures the area is experiencing. Over the weekend, about 2 feet of mud and debris flowed up onto Pilgrim Creek Road. Because of all the sediment, Mud Creek is now flowing across the road and not under the bridge. Pilgrim Creek Road remains closed until further notice. To access Shasta Forest subdivision, wilderness trailheads, and other areas of the Forest vehicles need to use the Esperanza Road.”
The Castle Lake to Heart Lake Trail was recently rerouted and improved. It’s a lot easier to both follow and hike. See my detailed blog post about the Heart Lake Trail improvements.
