Great Campground for Kids, Lots of Amenities

Decent sites with full hook ups. Little shade with small trees next to about each site. Gas, propane, laundry room, beach area, small boat rentals, good sized convenience store with ice, beer, snacks, milkshake machine, etc. Enough to do for a day or two without going to the water park. Overall…

Something for everyone

Great RV park. Lots of room and cabin rentals for folks that don’t have an RV. The fenced dog park was fantastic for those of us with dogs. A lake with beach area and an area for fishing founded it out! Would recommend!

Just stayed one night passing through Iowa. Very pretty Campground with colorful Kabin’s and a lake for swimming or paddle boats. Level sites but not much shade.

Surprised we did not get an escort to our site as is usual at KOA’s. Did not use bathroom facilities. Laundry needed attention as it…
