To reach the car park at the start of the walk from Pola de Somiedo, follow signs for “8 km Valle de Lago”. Pass the turn-off for the campsite and the small village of Valle de Lago. The car park is 8.5 km from the “Centro de Interpretación del Parque Natural de Somiedo”. Parking is available on both sides of the road in marked spaces.
(S/E) Continue on foot along the same road, passing through a hamlet until you reach a sign on the right indicating “Lago del Valle Por el camino de sombra”, meaning “via the path in the shade”.
(1) Ignore the direction indicated by the sign and carry on along the road until you reach a fountain. After the fountain, continue along the track reserved for livestock farmers. Signposts indicate thePR® AS 15.1 route. Carry on until you reach a Fork in the road and an ascending path.
(2) Ignore this path which climbs to the left and carry on straight ahead until you reach a junction on the right with a sign indicating “Pueblo de El Valle – Camino de Sombra”.
(3) Carry on to the left along the main track until you reach another sign indicating ‘Lago del Valle Por el camino de sombra’, which is the upper section of the shaded path. This junction marks the turning point of the circular route.
(4) Turn left again and carry on until you can see the crest of the dam and the lake. Head towards its eastern shore until you reach a small sandy beach.
(5) Continue southwards along the lake’s shores for a round trip to the Cabaña Cobrana, two thatched barns.
(6) Turn back towards the spillway.
(5) For the return journey, head towards the dam and walk along its base. At the end of the first concrete section, climb up the embankment and then descend again to rejoin the second concrete section of the dam until you reach its end.
(7) Turn right to follow the narrow path known as the Camino de sombra, upper section. Head down through the meadows until you come to a fork on the left and an uphill path.
(8) Keep to the right and continue the descent to the junction of the circular route.
(4) Take the path you followed on the way up in the opposite direction to return to the starting point (S/E).
