The path runs along the border between the provinces of Ourense and Zamora. The journey begins at Portela da Serra Calva (1,520 m), also known as As Lagoas das Tablillas, on the border of the Concello da Veiga and the Zamora municipality of Porto de Sanabria. Here, there is an astronomical observation area, as the area has a broad view of the sky and no light pollution.

The route runs alongside many small seasonal lagoons called lagoallos. The presence of these small lakes and waterlogged areas (called brañas) is an indication of these mountains’ glacial history.

The path visits the glacial lagoons of Ocelo and A Serpe, as well as the meadows and remains of huts formerly used by ranchers. From O Escavadoiro, the route climbs alongside the Xares river almost until its source. It then connects with other trails to get closer to the summit of Pena Trevinca.

The Integral da Serra Calva route is a total of 21 km, but you must reserve some strength for the return journey of the same length. Or go down to Vilanova or A Ponte through other connected trails.
