At the far end of Fontaneira leave the LU-530 for a small road uphill (direction Pandelo). You will pass the cemetery and then return to the main road to follow it for close to 1km. The camino then leaves the road in favor of a path on the right. As you descend to O Cádavo you will cross the Campo da Matanza (see note above).
Between Fontaneira and O Cadavo is a small plateau known as the Campo da Matanza. According to legend it was here that Alfonso II (the first pilgrim) and his troops defeated a Muslim invasion in the year 813.
