We camped here out of desperation. We'd intended to camp at Wild Rose, but the spring winds were too much for us. As we drove down off the mountain, we got caught in a dust storm and thunderstorm! The campground is just a big square of gravel and offers not much in the way of natural features. We parked our van right up to the perimeter where the sites back right up to dunes. After the storm, the kids got to go explore the dunes and that was cool.
This was the only campground in Lassen that was open at the time of our visit. It is a perfectly serviceable campsite in a pretty spectacular location and provided a nice home base for many hikes. The sites are not very private, but they are spaced far enough apart so even though you can see your neighbors they don't feel too close for comfort.
The family was split about this one. I thought it quite lovely. Our spot backed up to Union Creek and I love the riparian plant life. The kids love being next to the creek, but it was very buggy. One day I would love to come back to the area and hike on the Union Creek Trail.
