Can I swim in canals and rivers?
No, swimming in navigable canals and rivers is forbidden — it is only allowed in officially designated swim zones. In Flanders, De Vlaamse Waterweg forbids swimming and diving in the canals and rivers it manages: too dangerous because of shipping, suction at locks, cold shock and variable water quality. Swimming is only allowed in demarcated zones (with a permit). To swim outdoors safely, there are the officially recognized bathing waters: in 2026 Flanders has more than 100, whose quality the VMM monitors during the bathing season. In Wallonia there are dozens of supervised zones (24 for 2026, season 15 May–30 September). In Brussels, swimming in the canal is forbidden, but a supervised natural swim zone opens in summer 2026 at Neerpede (Anderlecht). Swimming in forbidden water risks a GAS fine.
📋 The rules
- Swimming and diving in navigable canals and rivers is forbidden (De Vlaamse Waterweg, SPW)
- Swimming is only allowed in officially designated/demarcated swim zones
- Flanders 2026: more than 100 recognized bathing waters, quality monitored by the VMM
- Wallonia: supervised swim zones (24 for 2026, season 15 May–30 September)
- Brussels: canal forbidden; new natural swim zone Neerpede from summer 2026
- The municipal police regulation sets the enforcement (GAS fine)
🔓 Exceptions
- In a recognised bathing zone with permission (an event, a long-distance zone) swimming is allowed, under supervision

- In Brussels the canal stays off limits, but a supervised natural swimming zone opens at Neerpede (Anderlecht) from summer 2026
⚠️ Penalties & fines
Swimming in forbidden water falls under the municipal police regulations: an administrative fine of up to 500 euros for adults and 175 euros for minors (since the reform of 8 January 2024; many municipalities still apply a lower rate). You can also be fined by the shipping police. What swimmers do not see coming: if you bring shipping to a halt or the fire brigade has to turn out, the cost of that operation comes on top. More important still: drowning, hypothermia and the suction at locks make wild swimming in canals life-threatening.
