We stayed at the group campsite at Allis state park. It comfortably fit our group of 17 and all our cars. We were able to fit 11 tents and park 9 cars all on the campsite. The group campsite came with 4 picnic tables, 1 fire pit and 1 small grill. There’s also a covered platform that I believe is called a lean-to. We used this area as our kitchen and we stored all our food and coolers here. We were able to fit 2 small rectangle tables, 1 large folding rectangle table and 1 small square table in the covered platform. Even with 4 tables we still had plenty of space to move around and cook our food comfortably. There is also a trail from the group campsite leading to the bathrooms attached to the pavilion. The only down side to these bathrooms is that there is no lights in them, so you have to bring a flashlight when it starts getting darker. Another down side to the campgrounds is that there is only 1 shower in the women’s bathroom and 1 in the men’s bathroom. The bathrooms with the showers are kinda far from the group campsite. We would drive to these bathrooms when we needed to shower. The showers are also coin operated. I believe 0.50¢ gave you a 5 minute shower, 0.75¢ is a 7.5 minute shower and $1.00 is a 10 minute shower. Because of the bathroom and shower situation is the only reason why I’m giving it 4 starts instead of 5. This camping ground is absolutely beautiful with many beautiful hiking trails, a big open field to play sports and things near by the camping grounds to do as well. Our large group loved it here and definitely plan on coming back!
