Our two children and grandchildren will

Our two children and grandchildren will be visiting us at Casa Le Crete, Ficulle, in October.  As the children are still very young (4, 2 1/2 and 1 1/2) we are interested in finding things that would be of interest to them.  Thought of a farm where they could see/pet or feed small animals.  They are too young for Scarzuola and Bomarzo.  Any thoughts???  Would be nice if the adults could enjoy a lunch as well....

Grazie,  Lisa

We are in south/west Umbria
