what campgrounds are available throughout the winter in the Big Bear area? And also of those, which are first come first serve and which are reservations?
Yep, I googled "big bear yellow post" and about the fourth result down was a Google maps doc that has A link to a map with them all listed and coordinates.
I got slightly turned about on my way out and I think I ran Holcomb creek and for sure finished by running down deep creek. Both seemed slightly boring on portals, never engaged a locker or aired down.
