I think this would be considered the main campground at Lassen. It has showers, a store, gas, etc. So if that's what you want, it is 5 stars. It also tends to be crowded and busy, which to me is a downside. The sites are very close together so hope you get good neighbors. Still, your in Lassen, so Yay!

There is plenty of hiking, great trails for kids, it's near the visitor center, the main road and lake, so if I were going with kids I would think it ideal. Get a reservation well in advance of your trip.
