The Budriolo Sinkhole

Highlight • Gorge

The Buca di Budriolo is a deep blind valley, formed near extremely inclined chalky layers, a natural wonder. From here, you will be able to enjoy a spectacular panorama from the opposite side of the hole.

Farneto Cave

Highlight • Cave

The Grotta del Farneto is one of the most well-known and important prehistoric settlements in the Bolognese area.
It can only be visited with a guided tour ( parks.it/parco.gessi.bolognesi/man.php )


In any case, it is worth a visit (even if it is closed ). The fresh air that comes out of it provides a bit of relief from the summer heat.

Fallen Tree on the Trail

Highlight • Trail

At the start of the trail there is a fallen tree. It seems balanced for the moment, but be careful when you pass under it not to get caught with your backpack, especially if you are alone
