Cycling possibility: You may use your mountain bike but be careful with cars on the stretch to Rioturbio.
Town Hall (20 metres): From the village centre, head towards the La Rabia lagoon through the drive Paseo de Solatorre. You will leave behind the majestic constructions of the Sobrellano Palace and the Pontifical University. Pass the roundabout Dr Santiago García Castellón. The sidewalk emerges onto a cycling path and eventually you will get to a new suburb characterized by recently built houses.
Rubárcena (40 metres)(km 1): when you get to the shelter, turn immediately left, follow the road that leads to an unsurfaced path, away from the houses. Ignore the path to the left and carry on westwards. As the path descends it joins a tarmac road that ends in Rioturbio. If you look to your right you will see a small and beautiful shrine. Continue straight on through the curving lane and eventually you will reach the bridge that crosses the marshland, known as Puente Republicano.
The la Rabia lagoon (5 metres)(km 3)(45′): This narrow road runs between the extensive vegetation of the marshland. For some time the predominant species has been the Baccharis halimifolia, a bush from South America, which has colonised a great part of the area, displacing native flora and thereby altering the ecosystem. It is an almost flat area, so follow straight ahead, cross a bridge and you will arrive at Rioturbio.
Rioturbio (10 metres)(km 4.5)(1h. 10′): This little hamlet is part of Oyambre’s natural reserve and displays a fine collection of tradititional houses. It is a small neighbourhood that leads to the outstanding woods in the Monte Corona forest.
