An exceptional raid that crosses the whole of Andalusia's white villages in 10 days of mountain biking on tracks and trails. The landscapes were very varied: Mediterranean, covered with cork oaks or olive trees to infinity, multicolored crops, speckled with white villages, flowers, white walls, touches of red, azure blue, ochre. And then mountains, nature reserves like Grazalema, its limestone karts and its hanging valley, or the Alcornocales park and its inexhaustible supply of cork, a reserve of corks from all over the world. There were fleeting encounters with deer, a manu militari escort by a mafia owner, but most often a warm welcome, of rare kindness and conviviality.

This will not be a favourite for vertigo sufferers, and you can avoid it altogether by staying on the main road (A-2226). However, the Corredor Verde de Dos Bahías is really beautiful.

Large reservoir. However, very flat. Actually doesn't invite you to swim :-)

This viewpoint is located on what was formerly an important Roman road that connected the Campo de Gibraltar with the western bay of Cádiz. It is located within the Los Alcornocales natural park, so it is not difficult to see these trees on the sides of the immense pastures.

Located in the Los Alcornocales natural park, the Almodóvar river runs only through the province of Cádiz and its flow is regulated by this reservoir of the same name. It is located just five kilometers from Facinas, a district of Tarifa.
