One country, three regimes: Flanders runs on marked bivouac zones (booking required), Wallonia bans forest overnights outside its designated areas, and Brussels-Capital is its own world. The short Belgian answer is: which region are you in?

This is not legal advice: it's what the official sources say, checked by hand, plus what I lived myself. Verify before you bet the fine on it.
One country, three regimes
First, the region
In Belgium there's no national camping law worth citing: forest and nature are regional competences. Flanders regulates access through 'toegankelijkheidsregelingen' and bivouac zones; the Walloon Forest Code bans temporary residence outside designated areas. Same question, two different laws — first check which side of the language border you're standing on.
- Brussels-Capital has its own regime (Sonian Forest included) and we haven't verified it at the source yet: until we do, this page covers Flanders and Wallonia and says so plainly.

Flanders
The Flemish baseline
In Flemish forests and nature terrain, default pedestrian access is on the paths. Leaving them to spend the night takes one of two things: the terrain's approved access regulation providing for it (a bivakzone), or the manager's written permission — requested at least 35 days ahead, and carried with you.
- The manager can close temporarily for fire risk, sensitive wildlife, works or hunting — the sign of the day overrides everything else.

The bivakzone: the pole still standing
Where the Netherlands dismantled its poles, Flanders keeps them in the statute: a bivakzone is, literally, the space up to ten metres around a pole intended for bivouacking. Written regional rules: at most three tents and ten people per zone, each tent 48 hours maximum, and zones are sited where no motor vehicle can reach.
- The 48 hours are the regional ceiling, not a guaranteed entitlement: each zone applies its own regulation, and ANB's is shorter (one night).
ANB zones: book it, one night
At the Flemish nature agency's (ANB) bivakzones the procedure is concrete: mandatory advance booking in their system — no proof, you leave —, tent up only between 18:00 and 10:00, a single night, arriving on foot or by bike. Fire only in the provided baskets and only when the day's fire-risk status allows.
- The live list of bookable zones (currently in Limburg, East Flanders, Antwerp and Flemish Brabant) is on their site — don't trust third-party maps: other managers' zones exist with their own conditions, outside this system.
Private Flemish forest
Private forest covered by the nature decree plays with the same cards: for an activity not in the access regulation — sleeping, say — you need the manager's written permission, requested 35 days ahead; they answer in writing within fourteen. A handshake with the owner doesn't replace the paper.
Proper camping (more than a bivouac) — Flanders
The bivakzone is for itinerant bivouacking, and the agency itself draws the line: camping means settling in longer, with more gear, and 'per the legislator, that belongs on regular campsites'. A complete legal route for an informal multi-night camp in Flemish forest we haven't found in the sources — unconfirmed, which is probably what you suspected.

Sleeping in the vehicle — Flanders
Inside nature terrain the engine is banned except on ordinary through roads — and bivakzones are deliberately sited beyond a car's reach, so the van-night in Flemish nature doesn't exist as a category. Lawfully parked on a public road? No regional rule resolves it: it's left to municipal and parking rules — unconfirmed.
Wallonia
The Walloon forest: outside the areas, no
The Walloon Forest Code settles it in one sentence: 'temporary residence' — under 48 hours — is banned outside areas assigned to that use. Pedestrians must otherwise stay on roads, paths, trails and areas. Translation for whoever arrives on foot: in the Walloon forest you sleep at the bivouac areas or you don't sleep.
Fine: €500–2,000 — computed criminal range (individual, at night, no other aggravator: €25–100 × 2 × 10); not an on-the-spot fine, and separate administrative routes exist.

The Walloon 'aires de bivouac'
The Walloon legal door: marked areas expressly assigned to temporary residence — under 48 hours and free of charge, by legal definition. Mind the word 'aire': parking and recreation aires exist too, and those don't authorise sleeping. What counts is the specific area's assigned function, plus its local hours, bookings and closures.
- Each area exists by authorisation of the Government-designated agent, with the owner's prior agreement — which is why the inventory is finite and changes.

Two routes with bivouacs built in
Wallonia has routes built for chaining legal bivouacs. Two verified: the Grande Traversée de la Forêt du Pays de Chimay, with 13 bivouac areas spread along the way, and Entre Lesse et Lomme, 78 km through the Ardennes with three areas every ~25 km — booking mandatory on its website, access 16:00 to 10:00 unless a municipal order says otherwise, and meant for itinerant hikers, not for settling in.
- The inventories (13 and 3) come from official tourism pages, not each area's designating instrument: expect hunting closures and check the live route before setting out.

Private Walloon forest: the 'ayant droit'
The Code's private-forest exception has a technical name: the owner and their 'ayants droit' — anyone holding a personal right over that forest conferred by the owner — sit outside the bans, within the limits of that right. It's not 'he said yes at the bar': it's a genuinely conferred right, and you'd better be able to show it.
- Nature reserves, planning, municipal and fire rules still apply on their own.
Beyond 48 hours — Wallonia
The whole Walloon mechanism — ban and areas alike — turns on 'temporary residence' of under 48 hours. An installed camp or a stay of 48 hours and up? The Code doesn't govern it through that route and we've verified no other: unconfirmed. That's what actual campsites are for.
Caravan and motorhome — Wallonia
A legal detail almost nobody quotes: the Forest Code expressly excludes caravans and motorhomes from its temporary-residence definition — so its article 19 neither bans nor allows you. The engine, mind, may only use roads, marked tracks and designated areas; and a parking area is not an overnight area. The real answer lives in municipal and traffic rules: unconfirmed at regional level.
Walloon nature reserves
Nature and forest reserves sit outside the Forest Code's circulation chapter (save their roads and trails): they run a separate conservation regime we haven't read yet. Don't apply the aires logic there — a reserve's answer belongs to that reserve, and for now: unconfirmed.
Sleeping for free was half the budget
€3.16 per person, per day. The trip's full accounts — and the playbook to do it yourself — are in the budget dossier.
