About

County

Welcome to Oacoma Flatts, a dispersed camping area right on the banks of the Missouri River in South Dakota. If you're looking for a peaceful spot to pitch your tent or park your rig, this place has got you covered. It's free to camp here, and you can stay for up to seven days.

One of the best things about Oacoma Flatts is the stunning river views. You can camp right by the water and enjoy the serene landscape. Some visitors have mentioned that the sunsets and moonlit nights are particularly beautiful. If you're into birdwatching, keep an eye out for woodpeckers in the dead trees along the shore.

While the area doesn't offer amenities like drinking water or electric hookups, it does allow campfires, so you can still enjoy a cozy evening by the fire. Just remember to bring your own firewood. Pets are welcome, so feel free to bring your furry friends along for the adventure.

Access is easy, even for larger vehicles, and the dirt roads are manageable with a 2WD. It's close to I-90, so you might hear some road noise, but most folks find it quiet and relaxing. The area is also known for its wildlife, so you might spot some interesting critters during your stay.

Whether you're passing through on a road trip or looking for a quiet spot to unwind, Oacoma Flatts offers a simple, natural camping experience. Just be prepared for the basics—no showers, no trash service, and no picnic tables. But if you can handle a bit of roughing it, you'll find this spot to be a peaceful retreat by the river.

Beats the Hell out of Walmart

Traveling from New England to PNW in mid to late April, none of the campgrounds were open, and no BLM or FS to the East. This was the first dispersed camping in this leg of our trip. Right on the shore of the lake. Beautiful on the shore with a near full moon last night. Just off the edge of town, but quiet. Only real down side was some very bright lights off in the distance across and down the lake.

Dispersed camping site

Great dispersed camp site a minute or two off of I90 (can hear the road noise). There were other people there when I stayed in August but everyone was quiet and kept to themselves. Felt safe sleeping there in my car as a solo female traveler.

Nice free easy access on the Missouri River

Nice, quiet (depending on your crowd) spot that is right on the banks of the Missouri. Easy access in and out, even in a 2WD. I'd you're in to birding theres some dead trees on the banks that attract woodpeckers.

Great spot on the Missouri River

We needed a dispersed place to stop overnight on a road trip. This spot fit the bill. We parked our trailer right next to the Missouri River. There were a few other people there but everyone had plenty of room and it was quiet.

Uncrowded and right next to river

Boondocking area along the Missouri River. Easy to get to off highway. Access via dirt roads.  Lots of wildlife.  Only downside is mild noise from highway depending on the wind direction.

Very Peaceful

This place was such an amazing peaceful stop. Camped right next to the river. Temperature was awesome. The only downside was there were ALOT of bugs that looked like ginormous mosquitos. However, they didn’t bite and stayed away with a small fire and moving a lantern at 10 feet away. Either way, did not ruin our trip.

Good quick road trip stop

The field and the river are nice and there’s tons of space, but when we arrived there were over 20mph winds so we didn’t pitch a tent or use sleeping bags since we didn’t want anything to blow away. It’s great that the site is free though and it’s a pretty easy stop mid road trip, but definitely better for RVs then tent camping (depending on wind).

Open area near the river

We pulled in as the sun was setting. Large open field area near the river. About four or five other campers but really far apart. Quiet with the sound of the water. Good place to sleep for the night.

Missouri Flats Overlanding Stop

This is a must stay camping area! A short drive off the interstate to a the wide open river flats. Room for dozens and dozens of campers but I only saw one other overnighter. Pulled up near the river and had a perfect night. Lots of wildlife with numerous bird species everywhere.

There are no services here but the river is close. Houses are across the field so not secluded but still a gorgeous place to stay.

Quiet Spots Down By The River

The best way to describe this place is to say it’s Labor Day weekend and there are still riverfront spots open. It’s very quiet, most spots are totally exposed to the sun, there’s 2 bars of LTE for Verizon and AT&T which is plenty good enough to work. There are multiple entrances but there is a pit toilet and picnic tables near the primary entrance which is about 100 yards away from the closest spot.

Perfection.

I just completed a 9 day mini epic trip with my Rav and my dog. From indiana to the Tetons and yellowstone. What a whirlwind. I was so grateful to find this little oasis by the Missouri river on my last night. I am currently nestled in my Rav listening to the cicadas and the river. I'm not sure if there is a potty as I have my own. My pup enjoying playing fetch and swimming in the river after being cooped up in the car the last 10 hours. It's a perfect spot to end my adventure. There r several places to park just follow any number of dirt paths to the river.
