The valley and woods are teeming with wildlife which if you don't see you can often hear.
But best of all are probably the fireflies. A magical experience. If you have never seen a Summer night flashing with fireflies you really should! Come in late May and June for the best experience. Take a look HERE to get an idea of what it is like.
And some you might not want to meet
Scorpion- common - best not to leave your clothes on the floor overnight! Sting not serious.
Snakes are present though not often seen and are always more frightened of us than we are of them, however enthusiasts can go and search for the following which have been seen over the years... Smooth snake, Whip snake, Viper, Aesculapian snake.
