No special access issues
Driving from Masua to Buggerru you'll find a sign indicating Cala Domestica. Well just 450 metres before that, on the right side (inland) there is a dirt road winding through the valley. Follow the road for 2.2 km, until a widening where the river has destroyed the road. From here follow the path going up and walk inside the gorge.
As the gorge gets narrower, after 5 minutes of walking, you'll find on your right-hand side the sector Istentales. After a few more minutes, just over a ford, you'll find the sector Piazza Pulita.
Keep on walking 400 metres, and pay attention to your left side. You can spot the crag only after you pass it, so go back and find the little trail that climbs up towards it (80 meters from the road)
