Pulo do Lobo Riverside Trail

The Pulo do Lobo Riverside Trail leads through the Guadiana Valley Natural Park to Pulo do Lobo, the Guadiana river's only true waterfall, near the town of Mértola in southeastern Alentejo. The trailhead is reached by car from Mértola, with the final approach road unpaved and best suited to a standard vehicle at moderate speed; informal parking is available near the falls. The route covers 11 kilometres round trip and takes three and a half to four hours, crossing flat to gently rolling schist terrain along the river gorge with under 100 metres of cumulative elevation gain and no technical difficulty. The surface is dry, rocky schist steppe for most of the walk, with a rockier, uneven stretch along the gorge edge close to the falls themselves where sturdy footwear and careful footing are needed. Shade is almost entirely absent across the open steppe landscape. The trail passes through habitat for Bonelli's eagles and black storks, both of which nest in the gorge cliffs, making this one of the better birdwatching stages in the Alentejo interior. At Pulo do Lobo the Guadiana river narrows dramatically and drops through a rocky gorge, the flow and spray varying significantly with the season. There are no refuge huts or water sources along the route, so hikers carry everything needed for the round trip. Because the reservoir-fed Guadiana is at its most dramatic when flow is high, this trail is best experienced outside the driest summer months, when the falls can reduce to a trickle.
