Coming from ROMA - TERNI: 

About half an hour after you have passed signs for Terni you will arrive at Spoleto.  Pass the first turn you see for Spoleto,  take the second exit just after the tunnel.  This exit will bring you to a roundabout.  Take the first exit on the roundabout and keep going straight for about 2km. You will see an Opel garage on your left, shortly after there is a turning to the left where you will see a sign for 'Oleificio Melchiorri'.  Take this left and then the next left almost immediately after that.  After about 400 mt you will see another sign for 'Oleificio Melchorri' on the right hand side.

Coming from PERUGIA - FOLIGNO: 

Take the first exit sign for Spoleto that you will find a couple of kilometres after the motorway finishes.  This will bring you to the roundabout and you follow the directions as left.
