We stayed in the wooded dry camping area of the Great Falls campground. It was $10. It would have been $20 with electricity. It was mid-week in October so it was pretty empty but most sites showed reservations for Friday and Saturday so be forewarned. We took a lovely 2.5 mile walk around the park which extends quite a ways down the river. Clean restrooms but low water pressure.

Stayed in the tent section with my teardrop. 50 is on a corner going in/out, but one of the larger lots. Downfall was it was basically dirt. Glad it didn't rain. Do not, I repeat, do not use the pit toilets in the tent section. Just plain nasty. I'll leave it at that. Down further by the RV section they have flush toilets and showers. Go there. In both areas, just a handful of sites that give you any room. The rest you are sitting on your neighbors lap. But will do in a pinch. Cool veterans memorial in the park itself.
