Langres a lovely place to visit, cycling and walking fantastic, great for birdwatching around lake and canal, and looks great for watersports.  There's even a beach across the road.  But the site itself is tired and needs some investment, it's not a four star site.  The sanitary facilities are dated, there aren't enough toilets and showers for the number of customers and no separate  washbasins with soap in toilet area.  As a result the standard of cleanliness isn't what it should be.  The shop is also disappointing given that the site is 5km from the nearest supermarket - fresh food would be really useful particularly for motorhome users.  Pitches are variable, none are level, some are very small, many lack shade and privacy.  Site seems predominantly to be used for overnight stays.  A real shame that the site isn't better given where it's sited, as we'd recommend staying longer than one night.
