🚗🚶♂️ On the bendy road that takes from Dorgali to Cala Gonone, when you've almost arrived at the bottom, there's a cemented road with the sign "Nuraghe Mannu". Drive 750 meters, stopping when the road does a second bend to the left. From here go west, entering the small gorge and following the rare cairns. Walking 15 minutes, you cannot miss the crag!
