Climbed this three months ago now, so my recollection is a little hazy. At any rate, parked to the east by the wells at the side of the road (north east of Cima la Piazzetta), skirting around the bottom of Cima la Piazzetta to reach the saddle between them, before making steady progress upwards alongside a wall which goes all the way to the top. At the top itself there is evidence of some sort of building or enclosure having been there, but long in ruins. Descended same way and headed up the eastern peak.
