It goes without saying that campsites in cities aren’t all that commonplace, and for those that do exist demand may be high because they are popular with families who take their cars on holiday - this will likely mean prices are a bit higher than what you might find in the countryside.
In France, the golden rule for finding good value campsites is to look for a ‘camping municipal’; that is, a basic, reasonably affordable campsite run as a public service by the local council. There is one that I’m aware of that fits this description in Paris, Camping la Haute Ile in Neuilly-sur-Marne (I know about this from planning a driving trip with friends a few years ago which didn’t quite come together in the end). It’s 5 mins from a bus stop or 2km from the nearest RER station.
Thanks eDM but I typed wrong over there
we do not want to pay anything for the camp site. we want to camp in the woods. That’s what I meant to say 🤪

That's not always allowed. Do check the countries you intend to visit where you're allowed to camp.
Brussels is not in Bulgaria… I suppose you mean Belgium?
Wild camping is not allowed in about all of west-EUR. Not just police but also criminals will think you are fine picking. Even if you get fined for doing it only once, you could have paid hostelbeds in all those towns instead.
BTW; BG=Bulgaria, BE=Belgium.
As you have a pass anyway the best way (IMHO=in my humble opinion) is to not leave train at main station in those giant cities, but take a slower local train that stops in smaller villages and get off there.
Other way to sleep for very little or even free: couchsurfing. This is basically helping poor other travellers to stay in your house/room, sleep on couch/ground/whatever. Seems to be quite populair among east_europeans.
A question like yours will not really get too much of tips in a forum like this-those who do answer regularly know most about trains and all things aorund that. Other forums (like the old but sadly now defunct lonelyplanet/thorntree) of like frugaltraveller seem better aimed at this.
