LegendNice Iowa State Park campground just outside of Grenell Iowa. On a lake. Hundreds of sites. So many of the non-electric test sites look amazing. The RV sites are very packed in with little to no privacy.
LegendPulled in from the main entrance on Stage Coach road - saw signs for tent sites to the right, so continued straight to RV sites. Found the little site with about 10 sites and only 2 other campers there. Found a nice place by the water and parked, hooked into electric.
Later took my bike for a ride and realized how many other sites there are around this lake. So many of them right on the water. A beautiful little spot. I was thinking of staying two nights, but discovered 2 ticks on my cat and decided to pull out.
Over night big rain came in and my power pedestal and fire pit were submerged in water! Choose your site wisely if there's a storm coming!
LegendBig beautiful camp ground right on the Des Moines River. All need to be reserved in advance at Recreation.gov
I selected my site based on its proximity to the river. Good choice, as I could watch the eagle and heron fish right from my site.
However the very busy bike/pedestrian path also runs right next to the site. So there’s no privacy. And the bridge that goes across the river is made of loose boards, so every time someone crosses there is a loud clanking sound.
Despite all of that, I did enjoy my experience here a very well kept campground. Big trees. Good enough cell reception for me to work. Electric hook ups, but no water.
ScoutThey show tent camping reservations allowed online and they even let you book a tent to Camp online for paying $32 but then when they come around and talk to you they don't say anything about not having a tent allowed and they don't give you the codes to the restroom and then they just close the office and go to bed and then at 11:00 at night the sheriff comes and tells you to grab all your stuff because there's no camping allowed and put you out on the street with nowhere to go and no more money cuz you wasted all your money on that stupid site that you didn't even get to stay at and then you realize that after you carried all your stuff over to the bar and had to sleep outside on the streets with your service dog when you have disabilities and you told them you have seizures that you had a seizure and now you have to go to the hospital and you lost your tent because somebody stole it so now you have nowhere to live because you're homeless and somebody stole your only house which was your tent because the sheriff kicked you out at 10:00 or 11:00 at night that was really great thanks that was the best experience in my whole life not really and thanks for putting my stress level so high that I went to seizures when people have disabilities you guys should be more accommodating and be more open and honest and be more willing to talk to people
GuideArrived at Reece Memorial Park in the early afternoon. I stopped by the Octagonal shelter at the south entrance of the park. This is a large shelter house with a fireplace in the middle of the building with several picnic tables.
I then drove down the road and entered into the west entrance of the park and followed it around the loop. There is a wide open area with a small slide and Merry-go-round, along with a couple of picnic tables.
I found, what I think, the best campsite in the park, and it was open. It sits along the creek and there was a fire ring there. This park is all primitive campsites, and so be prepared for that, although the description of the campground mentions vault toilets, I did not see them.
It was a very nice relaxing campsite, and the fact that there was no cell service, made it even better! There were a few vehicles drive through, and a little road noise, but I enjoyed my stay there. The creek was up, and it looks like part of the park might still be closed on the South side.
To primitive camp, the cost is $10.00 a night, and registration is with a QR Code, but since there is little to no cell service, it was difficult to get registered, so you may want to pay before you go.
GuideEverything is the same as reported in previous reviews. Good facilities and low price. Easy in and out.
ScoutVery friendly and clean! The bathrooms and showers are very nice. We enjoyed our short stay and will be back.
TravelerPark was pretty full, but they found us a spot for the night. Excellent pricing and the yards are BIG compared to other places we've stayed. Would definitely come back
ScoutTesting out a new set up and this has full service with electric, water and sewer line.
