The Fraxos or Fraxou forest lies close to Lesini, covers almost 58 hectares, and has been declared a Monument of Nature. In reality it is all of what remains of the dense riverside forests that used to cover the Aheloos basin. The forest is replete with laurel and silver birch trees, while creeping plants like Rough Bindweed and Black Bryony climb the tree trunks to create a greener, dreamier landscape. So far, logging has not touched this valuable forest, which is home to the otter, as well as several bird species such as magpies, woodpeckers and others.
