Morci-cuentros, día 3

Leave Oña on the N232 road towards Santander. There are tunnels, and it is advisable to wear vests or something fluorescent. You can veer right to avoid the last tunnel. You need to climb a couple of kilometers, although it is gentle. While descending, ignore the exit to Trespaderne on the N629 and follow the N232 marked as Valdenoceda, up to Cereceda.

Entering the village on the left, there is a sculpture park by Carlos Armiño, a local artist. In the village, you should take a local road to the right, which is marked as Panizares. You need to go uphill, and just before the entrance of a painted tunnel, there is a siphon a few meters below the road. This is marked as Fuente Oro Maria.

Exiting the tunnel, on the right is the Cereceda reservoir which is very beautiful. Follow the road through various villages until Puente Arenas where you can eat and swim in the Ebro river.

Then you must return to the entrance of the village and cross the bridge towards Valdenoceda. Exit onto the N232 again. After the village of Valdenoceda, before the bridge crossing the Ebro, you need to gather and leave all together because it is a very dangerous stretch until Incinillas. You should ride in double file and be very careful on the tight curves.

Continue on the national road to Villarcayo; the camping is on the other side of the village towards Bilbao.
