Park on the small road near La Jaya bridge.
(S/E) Leave the car park and head south-west along the unpaved track. Walk for about 250 metres.
(1) Then turn right and head up the paved path, the Ruta del CaresPR®®-PNPE 3. This is the most difficult part of the route... Continue westwards along the path, which becomes stony.
Pass the ruined building via the winding, stepped path. Reach Los Collados and begin the descent. Leave the Canal del Escalero behind, continue on and cross the Riega del Saigu ford.
(2) Go through the tunnel whilst continuing towards Caìn. Pass La Viña; further on, the path widens for a few dozen metres and runs alongside the canal.
Pass a bridge (Puente Pando) below and, on the right, the Canal de Culiembro. A little further on, there is another bridge (Puente de los Papos) in ruins. Continue through a series of tunnels.
(3) Pass the De Los Martinez footbridge, built following the collapse of a tunnel. About 400 metres further on, you reach the end of the province of Asturias and the start of the province of Castilla y León.
(4) Leave the Canal de Cabrerizas on your right and cross the River Cares via the bridge (Puente Bolin) to reach the right bank. Continue for about 250 metres.
(5) Take the bridge (Puente de los Rebecos) to return to the left bank.
(6) Pass through a long tunnel (a torch may be useful) with large openings, which leads to the Caìn dam. Cross the dam and continue along the right bank.
(7) At Los Pinderos, leave thePR®®-PNPE 3, cross the bridge and turn left towards Caìn.
(8) Start the return journey via the same route.
(7) On leaving Caìn, cross the bridge and follow thePR®®-PNPE 3. Then cross all the bridges and go through all the tunnels you used on the way out, continuing without leaving this path.
Leave Llano de la Sota on your left. Pass El Roblo and begin the climb towards Los Collados, then descend towards Poncebos. As you pass the recycling bins, you can dispose of any rubbish.
Head towards the Pont de la Raya (S/E).
