Very beautiful and there is something to discover everywhere, a park located in the forest. It is worth a visit.

There is a lot to discover here. Many sculptures spread out around the area invite you to climb, swing, think, laugh, understand, listen. My absolute favorite in the cave: Man-Fred the Book-Man with an iPad.
