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.

In the heart of the Algarve, perched on a hill on the right bank of the Guadiana River, Castro Marim Castle holds centuries of history and battles. Although human presence in the region dates back to prehistoric times, it was here that Romans and Muslims found a strategically valuable vantage point, taking advantage of its privileged position. The imposing fortification you can visit today (for a small fee) was built in the 13th century by order of King Dinis, serving as a defensive bastion against invasions and as a watchful sentinel on the border with Spain. At the top, the reward is a breathtaking panoramic view: the town of Castro Marim at your feet, the shimmering salt flats, the bridge connecting Portugal and Spain, and, in the distance, neighboring Ayamonte.
