Humbug campground is one of my favorite in the area. Breitenbush creek flows next to it so you can hear the churning water all night. That area receives a ton of winter rain and the vegetation is so lush it feels like a rain forest. If you want to camp in this area and avoid all the commotion of camping right on Detroit lake, this is the best place to do it. It fills up really fast on the weekends though, so reserve early or go on a weekday.
