Hi there—we had a reservation mainly because they have both dry camping and full hookup and we needed the hookups and didn’t want to chance it. That said, there were a lot of empty spaces (with and without hookups) for the first few days we were there. Then on the weekend things started to fill up and I think they were fully booked. They also have electric/water sites. The dry camping sites are right on St. Mary lake and are beautiful, but be warned the wind off the lake can be pretty intense (even in summer). Beyond that there are no good/bad sites since you’re basically out in an open field of grass. Happy camping.
