Very pleasant crêperie, did not use the campsite but there are lovely walking routes around the lake and along the Rigole d'Hilvern which actually starts near the lake.
Clean sanitary facilities, friendly staff.
But: large dogs running freely and the tenants opposite me (after 120 km of cycling) were unfriendly and bordered on being rude. All signs of lack of interest in their job.
Since I speak French, I was able to avoid being the only one having to eat my crêpes outside in the cold and in the morning I had to wait until 9 a.m. to unplug my battery.
The only unpleasant experience out of 10 overnight stays during my bike tour from Bonn to Quimper.
