We love camping at Grant River!
The camp host, Sandy and her husband Frank are friendly and helpful. The rangers that drive and walk through always wave and say hello.
We have met many friendly fellow campers.
We go to Dubuque to the lock and watch barges go through. At Cassville, you can take the car ferry across to Iowa and drive along the hills overlooking the river. The Driftless area of southwestern Wisconsin is beautiful.

On the plus side, beautiful views of the Mississippi from camp, great roads in the area for motorcycles to ride, and extremely reasonably priced. Bathrooms, showers, and grounds were average. On the negative side, trains rumbled through, blowing their horns, probably twenty times a day, including a half dozen times each night. They were loud enough that you couldn’t hear each other speaking while they were passing by. Additionally, the barge flies were swarming and covering everything that wasn’t moving, but at least they didn’t bite and there were no mosquitoes. Despite the bugs and noise, somehow, it was a nice place with nice people so I would recommend staying there.

Trains run very close by pretty much all the time. Other than that, like other COE campgrounds, sites are well spaced and the price is right.

Take the ferry at Cassville and enjoy great ice cream in Guettenburg

A beautiful spot, but literally right next to a train track with trains blowing their horns all night. Many times more than one per hour. Not a great night for sleeping!

Saw a ranger once only. This park is neglected compared to previous years.Also not a fan of the upcoming check-in system. Not everyone has a smartphone. The park at DeSoto is much nicer.

Nice level concrete pads. Lots of shade trees. Great bathrooms, nice showers. Beautiful sunsets and views of the Mississippi right from your camper. Well taken care of COE campground.

We always enjoy staying at Corps parks. The grounds are kept clean. Restrooms were clean but the toilet tissue has alot to be desired. The inability to fill water tank at a clean water source at a central location is a challenge. Then you have to find a water spigot and potentially block the one lane road while filling. Or being stuck behind someone that is filling. Also, at the dump station, fill in with black top to make it a straight on shot. That curve s just ridiculous. No body wants to do that and then not be straight at the dump. Just do it.
