We spent the nights of the 19th and 20th here.
US Forest Service campground, primitive, no hookups and only vault toilets and garbage dumpsters for amenities, but a terrific scenic lake in the middle of the woods. Nearest town was probably 25 miles away (Seeley Lake), and cell signal ended about 15 miles before we reached the lake, so this was about as off grid as you can get.
