Three stars is a generous rating of this park, especially if your plans are to camp. The campground is smooshed together, one space on top of the other. There's a stretch of grass nearby that can have tents plopped on it but there are no other amenities for anyone; unless a single cold water sink and two toilets count.
I was told normal rates are $20/night but that sounds high. For Eclipse week it was $60/night and that's way excessive.
Access to the North Platte River is pretty much a disaster with a rutted "road" ending at a pile of dumped broken concrete. It's dangerous to walk through since each piece can be unstable and it all has a lot of trapped plastic in suspicious mud. I'm not a wimp but my dog joined me in being unwilling to pick her way through that.
I imagine the only time the place is used for camping is county fairs and eclipses. Otherwise get on your detailed mapping information and find something better.
Our stay here was great. The RV pads are all new with water hookups and 50 amp, 30 amp, and 15 amp power. There's plenty of room separating the 14 sites. It's first come, first served, $20 a night with an instruction sheet to guide you through paying and calling the city 24/7 to get the water turned on. Free RV dump site on the north end of the park.
