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.

What's particularly interesting about the Xerez stone group is its square shape. The menhir is located in the center, surrounded by smaller stones. A concrete path leads from the Orada Monastery to it—is this really necessary? A regular path would certainly have sufficed. The entire area appears very neglected.

You can access Pulo do Lobo from either side of the river: from Aldeia da Amendoeira, on the Mértola-Beja road (left bank), or from Serpa, in the village of Vale de Poços, where you'll find signs indicating exactly where to turn right (right bank). Both paths are well signposted, and both have several viewpoints. The best view of the waterfall, however, is undoubtedly from the viewpoint on the right bank. Further ahead, you'll see Pego dos Sáveis, the spot where the water suddenly calms down again, forming a tranquil lake.

The Xerez Cromlech stands on open land, close to the Convent of Orada, and with a view of the walls of Monsaraz. It is the second "home" to prevent it from being submerged by the Alqueva dam. The 55 granite menhirs of the Xerez Cromlech have already been to other places because they were moved here, to the vicinity of the village of Telheiro, in 2004, to prevent submersion by the Alqueva dam. The cromlech was in front of Monte Xerez, close to a dolmen, about 5km from Monsaraz.
