We stayed here in February and used the campground as a home base for a XC ski trip. The winter camping area is in the South Campground in what is the summer-time day use area. Tents can set-up near the water in the trees. Vans and RV have to stay in the parking lot. We only had two other groups camping on a Thursday night. Apparently it gets busy even in winter during the week-end.  There was an open heated bathroom with shower and a warming hut with a woodstove (not on and no firewood) used by skiers. Views are awesome and access to groomed ski trail network was also right off your steps.  Decent AT&T cell reception.
