Pulo do Lobo is a waterfall 17 km north of Mértola, in the Lower Alentejo region of Portugal.

[1] This waterfall is located at an altitude of between 33 and 35 metres in a very narrow gorge in the River Guadiana.

[2] Pulo do Lobo is the most dramatic stretch of the Guadiana, where the "river boils between harsh walls, the rushing of water, hit, flow and wind gnawing a millimeter per century per millennium, a nothing in eternity" as José Saramago, one of Portugal's most famous writers, wrote.

The Pulo do Lobo is formed by the Guadiana river which separates Spain and Portugal.

The waterfall is a very majestic sight and is full of native wildlife.
