Kettle moraine is great, especially for hiking. We stayed at campsite 907. The lower 900 loop in general had quite a few sites that could be used as group sites. Two sites that were completely adjoining or had very little separating them. Our site specifically was pretty small and did not have very much coverage from the drive. I personally like a more secluded feeling site. We did walk around a few of the other loops and it seemed the others were not set up this way, the upper 900’s and 800’s both had a bit more seclusion. In short a great stay, great restroom facilities, showers, etc... a nice little beach on a huge lake, family friendly, with tons of the Hiking trails near by. My suggestions would be if you are with a larger group or like to be social try something on the lower 900’s loop and if you like a little more seclusion perhaps the upper 900’s or 800’s.
