Quiet basic site, but walkable (or cycle, there is a cycle path the entire way) directly into Bruges centre.
The toilets are clean with soap and a dyson air blade dryer, and showers are clean, hot and powerful enough. Friendly reception, and a self check in if you arrive late.
Pitches are quite small. Separate tent field unless you want electric, but couldn't be better placed for a city break in such a beautiful city.
No play area but adjacent to a forest with a fitness track and lots of climbing ropes etc.
Well under 2 hour drive from Dunkirk makes a weekend break possible.
