The good news about camping in the “off” season is fewer crowds; the bad news is that many of the perks (concessions, boat rentals,etc) are not available. After summer during the week, the only campground available is Quartzite (I believe there are two others plus a group campground). The bathrooms in Quartzite were new and very clean. Trails are plentiful and some are quite challenging but offer fantastic views. Trails are well marked. We were there on a cold, cloudy day but I think it is the best time to visit.Of all the Wisconsin State parks we have camped in recently, Devil’s Lake is the best!
