This is one of my favorite group sites of all time. The main reason is because each group site is fairly secluded and is not part of the main campground. It feels like you have an entire campground to yourself.
There are two group sites here, and I have stayed at both of them. Each group site is a loop with multiple trailer spots. There are also quite a few areas for tents as well. We could have easily fit 7-8 RVs in a single group site, and could likely fit more if you wanted to squeeze them in. Our group also had a class A motor home which fit easily.
Each group site has plenty of tables and a large fire pit. There are 5 rows of tablesin each suite. We had a group of 15 and we only used one row of the tables.
There is water available at each group site. There isn't a way to attach a hose, so filling the fresh water tank on the RV is slow but it still works. No electricity or dumping station is available.
There are pit toilets at each group site. These are cleaned daily.
The lower site (which I believe is group site B) is slightly better than the upper group site. This is because the lower site has less traffic. The upper site is next to the main road and you have to drive next to the upper site to get to the lower site. The lower site is also closer to the lake.
