There is. You 'll find more infos here (i connot post url links yet, so ...) : "3w dot scoutisme-francais dot org
If you contact them, they'll tell you about the one in you region.
I guess Beaver scouts would be like Scouts et Guides de France (catholic) you'll get more info at "3w dot sgdf dot fr" or Eclaireuses Eclaireurs de France (nondenominational) with more info at "3w dot eedf dot fr"
Just get used it it being called "scoots" - I still chuckle when I hear people talking about the "scoots" here. It's just the way the French pronounce "scouts" but it does sound kind of funny to us anglophones.
