The trail starts near the bank of the Riu Cannisoni stream, near the junction with Trail 112. You will walk on a wide, well-marked mule track that soon leads to crossing the stream over a small wooden bridge, then continue on the right, parallel to the course of the stream. The trail continues on level ground, under scattered holm oaks, until it reaches the Fonte s’Acqua Frischedda spring, now entirely underground.
