We stayed at the group campground. Individual sites are first come first served, but the group site can be reserved for up to 40 people. It's HUGE. It has your own private men and women's bathroom, a large wash bin, two fire pits, and two grills with covered picnic benches. It also has its own parking lot and entrance/road where you likely won't interact with other campers. Lots of trees to hammock and the ground is flat and grass. It's about a 2-5 minute drive from the visitor's center and several trail heads. I would highly recommend for large groups that want some privacy.
