Guadiana Valley Natural Park, Nature park in Faro district, Portugal.
Guadiana Valley Natural Park covers 69,700 hectares in the Baixo Alentejo, spanning the municipalities of Mértola and Serpa in Beja district. It follows the Guadiana riverbank and takes in the historic town of Mértola. In the north, at Pulo do Lobo, the river drops about 20 metres through a rocky gorge.
Mining activity shaped this region from Roman times through the mid-20th century, when operations finally ceased after continuous extraction. The area was later declared protected to safeguard its ecological value and natural features.
Local farmers shape the valley through traditional cultivation of olives and grains, maintaining farming methods passed down through families over many generations. This way of working the land remains visible today and defines how the landscape looks and is used.
Several marked trails crisscross the park with free downloadable maps and GPS data available before your visit. Wear comfortable shoes and bring plenty of water, especially during the hot months.
Pulo do Lobo, in the park's northern section, is where the Guadiana drops about 20 metres through a rocky gorge. The site is noted for its geological interest. A flow gauge tower there has been reached by the river only twice in 50 years.
