Another Thing to do is watching the moles or hiking in the forrests around. Maybe you come across some deer or other wild animals. It is also possible to hire a horse.
Gro? Breesen is on the Bicycle Path from Berlin to Copenhagen. So, when you pass Gro? Breesen, it would be nice to make a stop here. you can even stay overnight at the nice small hotel.
Favorite thing: Gross Breesen is about 50km from Schwerin or Rostock and 170km away from Berlin or Hamburg. Public transport is almost not available.
