We've just stayed 2 nights at this Municipal site close to Schengen (no we didn't visit the European Celebration Centre!) https://www.siercklesbains.fr/camping/le-camping.html
17€ per night (cash only) but right on the river bank.
Reception closed 12 to 3 and old school form filling to register.
Easy walk into the old town.
