South of France near Carcassonne. Sleepy village. We mostly:
Swam every day in a free municipal pool, lake or river.
Had picnics in various places.
Climbed up huge Cathar castles (Peyreperteuse, Montsegur and Puilaurens were favourites, Queribus was just too damn hot that day!).
Carcassonne itself was amazing.
Went round two huge caves.
Jazz festival in tiny mountain village.
Medieval festival in an old castle. We saw jousting and ds tried archery wearing an archers glove, saw a falconer in action.
Pizza from the pizza van in our village.
Flea markets where DS picked up some crap with his pocket money 
Card games in the evening, eating dinner outside.
We're lucky we can rent a friend's house cheaply and it's only a 3-hour drive from where we live. Otherwise we've lived camping in Spain, especially around Gerona (Olot, very small campsite next to a field FULL of bunnies, and in Huesca and Horta de San Joan which has a fantastic bike route and lake to swim in, too).
So for us: nature, biking, swimming, festivals, castles, history, great food, foreign traditions, walking the dog! We're simple folk
