This spot is great, plenty of space, quiet, great views of Mount Shasta, easy to access. Lots of spots tucked away to park next to, and even more tent spots you can walk to hidden just off the drivable areas. Saw about 5 people camping around us, mostly in cars with tents and some vans. There’s more than enough room for many people. There’s also a small creek you can bushwhack to to the east, and castle lake is a 30 min walk up the road.
I would probably not recommend with a trailer. I made it down with my Tacoma and a 12ft travel trailer but it was a stretch. Super easy to get in, but took a long time to turn around and get back out. Anything bigger than and you’re probably stuck. Other than that it’s perfect!
