Grass Lake State Forest Campground Grass Lake Dam Road, Thompsonville, MI 49683

"Classic forest campground, site are well separated, lots of trees (and bugs, beware) with a few sites sitting right on the river. As with most (all?) state forest campgrounds, there is no power, no dump stations, and vault toilets. Water is available via pitcher pump (kids will love this), and there is a small weir/damn on the river, the river downstream from the dam is shallow and a fun place for water play. It's several miles off the beaten path and down a few dirt roads, but Google will get you there. Most RVs, maybe up to 25ft, can get in here fine."

"The 5 star rating was from my experience in 2018. I camped there just this past weekend and would only give it 3 stars now. The place has gone downhill. A lot of trash in the fire pits, multiple bbq's are missing with only the jagged end of a post sticking out of the ground (BIG SAFETY HAZZARD), and the weed and grass is darn near waist high in the camp sites!"

"Nice. Outhouse was clean and had a garbage bin in it. We were there for a canoe race that was the turning point."

"Nice primitive quiet camp This is a great little find.  All sites are first come first served and paid via an envelope into a lock box.  They do come around pretty much every day to check that you paid, so make sure you stop and pay up.  These sites are not like the state run campgrounds where you're packed in like sardines!  You have space and depending on which site you luck out with, you won't be able to hear your neighbors.  The sites that are like 8-11 (i think) are the best ones and you have more privacy.  But there are other sites directly on the water.  I was there for the July 4th long weekend and there were only like 5 sites occupied, but when we had called before showing up, they said some weekends they do get full. There is a well hand pump for water.  I'm not sure if i would drink it though…I saw no mention of whether it was potable or not.  But I used it to wash my hands, dishes and wash my hair. There are at least 2 vault toilets.  They have plenty of toilet paper, and aren't that smelly. The road is a dirt road to get there.  But there are lots of ATV roads on the way to the camp ground - so make you stay on the all dirt road to get there instead of turning onto a dirt ATV trail with lots of grass in the middle.  You don't have to have a 4 wheel drive to get there or anything, but just take the road slow so you don't break an axle. Bring a bike or kayak and enjoy the solitude while you're there!  It's great! There is a dumpster to dump your garbage on the way out. The site was relatively clean, but there was some litter that I could tell had just blown out of someone's car or something.  So leave the place cleaner than when you showed up and pick up the trash. All sites have at least one picnic table, a fire ring and a grill.  But no grate to put over the fire pit, we brought charcoal to cook with or transferred hot coals from the firepit. I have AT&T and had full cell service when I was there, so that made making evening plans easy."
