Overview
Alferce sits about 8km east of Monchique town, on a hillside in the Serra de Monchique where cork oaks and chestnut trees close in around a handful of whitewashed houses. The village has around 390 residents and the unhurried feel of a place that exists for its own reasons rather than for visitors. But two things make the detour worthwhile: a classified Bronze Age hilltop fort above the village, and a wooden walkway through a gorge the locals call the Devil's Ravine.
The parish is one of the Algarve's smallest, and its economy runs on cork, medronho distilling, and small-scale agriculture. This is the mountain Algarve at its most remote — closer in character to the Alentejo hills than to the beaches 40 minutes south.
Cerro do Castelo
The Cerro do Castelo de Alferce (also known as the Castle of Pedra Branca) is a fortified hilltop above the village, classified as a Site of Public Interest since 2013. The site has been occupied since the Bronze Age and was later transformed into a fortress during the Islamic period. Archaeological excavations have uncovered material from multiple periods of settlement, making it one of the more significant pre-historic and medieval sites in the western Algarve.
Little remains visible above ground beyond earthworks and foundation traces, but the hilltop position gives views across the Serra de Monchique that explain why people have chosen to defend this spot for over three thousand years. The walk up from the village takes about 20 minutes.
Barranco do Demo
The Barranco do Demo (Devil's Gorge) walkway is Alferce's most visitor-oriented attraction. The 2.4km out-and-back trail follows wooden walkways and steps through a narrow, shaded gorge carved by a mountain stream. The route drops through dense vegetation — ferns, ivy, mosses — into a ravine that feels more Atlantic island than Algarve. The walkway is well built and signposted, though sections can be slippery after rain.
Start from the trailhead signposted from Alferce village. Allow about an hour for the full return walk, more if you stop to photograph the gorge. The trail is not circular; you return the way you came.
The church and village
The Igreja Matriz de São Romão de Alferce dates from the 16th century and sits at the village centre. Beside it, a former parish house has been converted into a small regional museum with local ethnographic displays — tools, textiles, and objects from rural life in the serra. Opening hours are irregular.
Around the church, Alferce is a quiet scatter of traditional houses, garden walls, and the sound of chickens. Local artisans practice basketry and weaving, and the surrounding cork oak forests support skilled cork workers. Medronho (the fierce arbutus berry spirit) is distilled in the parish as it has been for generations.
Getting there
By car: From Monchique town, head east on the M1258 — roughly 8km, about 15 minutes on a winding mountain road. From Faro, allow around 90 minutes via the A22 and the Monchique road. There is no bus service.
The road is paved but narrow. Parking at the village and the Barranco do Demo trailhead is limited but usually sufficient.
Practical information
Alferce is a half-day excursion from Monchique. Walk the Barranco do Demo gorge, see the church and museum, then drive or walk up to the Cerro do Castelo for the views. A café in the village serves coffee and basic food, but for a proper meal head to Monchique town or Caldas de Monchique.
The mid-summer fire risk in the serra is real — trails may be officially closed in July and August. Spring and autumn are the best seasons. For a full day in the mountains, Marmelete is the next parish west and pairs naturally with Alferce.
