About
From the MI DNR Porcupine Mountains website:
Union River Outpost is a small three-site rustic campground located on the Union River. The campground offers solitude and a camping experience unlike a typical modern campground. Union River is a classic UP trout stream. The sites are ideal for tent, van or compact campers.
There is a vault toilet, but no running water is available at any of the outpost campgrounds. Fill up at park headquarters or visitor center.
