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 1 kilometres, passing all the other sectors. Pass a wide scree on your left side and immediately after is the path that climb us to Il Piccolo Canyon (50 meters from the road)
