Itinerary: A1, M1, O1
The Bus from Nuoro (A1, O1, M1) will probably make several stops as it passes the lower part of town of Orgosolo and then winds its way up onto the near level Corso Vittorio Emanuele which is the main street of the town. A short distance along the Corso the bus stops in a small tree-filled Piazza which has a school on the left and views over the lower part of town and the hills beyond to the right. This is Piazza Caduti in Guerra and is the best place to get off the bus.
The murals start form this Piazza and continue along the Corso, and in the streets to either side, for a few hundred metres. Once you arrive at the Banco di Sardegna on the left-hand side the frequency of the murals starts to reduce, however they continue to the far edge of town. As you explore along and around the Corso you will also find a few handicraft shops and shops selling Sardinian food products. You might also stumble across a few interesting examples of old traditional architectural styles in the back streets. You only need an hour or so of wandering to see most of what there is to see.
It may not be possible to find maps of the town on the net, but there is a street map of the town posted on the wall of the School building in the Piazza Caduti in Guerra (when it hasn't been defaced to the point of being illegible). Neither is really needed, however, as it is difficult to get really lost.
The Bus back to Nuoro stops at the same Piazza where you alighted upon arrival. If you didn't buy a second ticket at Nuoro for use on the return journey, then you can buy a ticket at the small delicatessen (no sign outside) located a short distance in the opposite direction along the Corso Vittorio Emanuele from the Piazza in an easily identifiable blue and yellow building on the left hand side.
There are several Bars located along the Corso but some close for lunch.
