From Lincoln, MT, take State Rt. 200 east 6.5 miles to campground sign. Turn right at sign, onto a gravel road, and go 0.5 miles to campground.
Please know that this is a really nice, 19 site campground and not just a picnic area as Goggle is representing it. There's a host on site, ultra clean vault toilets, and running water available at unthreaded taps around the 2 loops. Stayed here over the 4th of July and it was not full. $8 a night-$4 with a senior pass.
The campground is usually open through hunting season. It has back in spots for RVs but no water,sewer, or electric hook-ups. Today I took the dog down there because my road was so muddy and the road at aspen grove is much better.
Nice quiet campground. Out spot was right on the Blackfoot river. Caught a few cutthroats.
Great spot to pitch a tent. Beautiful scenery. Lots of tress and bushes between sites to give privacy. A couple vault toilets and a few water spigots. About 10mins east of town and less than 2 mins off the highway. Easy access and a great stop on a road trip.
