Not every closure is a bad thing. I know – coming from me, that probably sounds surprising. But hear me out.
The San Dimas Experimental Forest, tucked into the hills north of Glendora in the Angeles National Forest, has been closed to public recreation since March 23, 2026 – and unlike some closures I could name, this one makes sense to me.

Public Service Announcement:
As the popularity of overlanding continues to grow, Subaru’s presence celebrates owners’ love of outdoor adventure and the camaraderie it builds.
Forest managers restrict summit approaches after heavy snow and rescue operations — check official alerts before heading into the San Gabriels.
Forest Service signs off on new e-bike branches, restroom-equipped parking and wayfinding. Construction slated for June 2026.
