Great dispersed spot near Lassen Volcanic NP
We found this spot based on advice of the rangers in LVNP. Overall a great place to camp if your looking for a free option to camp/boon dock very close to the park.
Right when you turn off 44, go up a small hill, maybe 100m, then there is a clearing on the west side of the road. There is a perpendicular dirt road at the clearing (running west/east) with several spots to park a van, trailer, or even smaller RV. We saw four distinct sites where people had made fire rings—however due to the number of pine trees the ground is covered in a thick layer of pine needles— make sure you sweep at least a 20’ fire ring down to dirt around the rock pit before you make a fire. You can also hear noticeable road noise from 44 in the front spots so not super secluded.
Many of the sites we checked (near the entrance and deeper into the woods) had bumble bees coming out of holes in the ground so be careful picking your site, particularly at night so you don’t wake up to an unpleasant surprise.
Going further south down the main road you can find many other more hidden camping spots deeper in the forest, but the road is rougher and only suited for a 4x4.
