The best MTB trails around Sanlúcar De Guadiana

The Great Guadiana Route (GR15) is a long-distance linear hiking trail (approximately 65 km in the Algarve, with extensions in the Alentejo) that follows the Guadiana River, connecting the Algarve coast (Vila Real de Santo António) to the mountainous interior (Alcoutim and Mértola), crossing diverse landscapes (mountains, Barrocal, coastline), cultural and natural heritage, making it ideal for hiking and mountain biking, with connection points to other routes such as the Via Algarviana (GR13). 👍🥾🦯

High on a hill near Afonso Vicente, stand the Lavajo Menhirs, Neolithic stone sentinels that have guarded the silence of this valley for over five thousand years. Carved in greywacke and engraved with circles and dimples, these monoliths seem to align themselves in an ancient mystery. Recovered and restored in 2004, they have returned to their original location, inviting passersby to imagine a time when the stone spoke to the sun.

Along the Guadiana, the path meanders serenely, following the river's slow rhythm between hills of olive, almond, and fig trees. A former river of fishermen and miners, the Guadiana, called the "river of ducks" by the Romans, continues to connect Alentejo with Algarve and Portugal with Spain, a tranquil mirror of southern history and life.

The castle sits atop a hill overlooking the Guadiana River. The river forms the natural border between Portugal and Spain.

Alcoutim Castle was built in the second half of the 13th century, under the reign of D. Sancho II. This castle played a crucial role during the Reconquista and the War of Restoration of Independence. In the 20th century, it was subject to conservation and restoration. Currently, it houses a museum that displays the rich archaeological heritage of the castle and the surrounding region, including pieces from the Neolithic to the Modern Period.

Unfortunately, we were unlucky and were at the castle on a Monday, but it is closed then.

We just walked into a hunting party on Sunday. Watch out for the signs. Hunting is allowed on Sundays and Thursdays from mid-August to the end of February

The Zahurdón mill is located at the end of El Santo street, in Villanueva de los Castillejos. Typical old mill and a pleasant landscape with a picnic area and a nearby park.
