Serra (Mountains)

The forested interior of cork oak hills, thermal springs, white hamlets and a rural Algarve that most visitors never discover.

The Serra do Algarve, the mountainous interior that rises behind the coastal strip, is a world apart from the beaches and resorts. Two principal ranges define the landscape: the Serra de Monchique in the west, reaching 902 metres at Foia, the highest point in the Algarve, and the Serra do Caldeirao in the east, peaking at 589 metres at Pelados. Between them lies a rolling hinterland of cork oak woodland, eucalyptus groves, citrus orchards and small farming villages that feel closer to the neighbouring Alentejo than to the coast below.

Cork oak is the defining tree of the Algarvian interior and the foundation of its traditional economy. Portugal produces roughly half the world's cork, and the Algarve's inland hills are covered with sobreiros whose bark is stripped every nine years in a careful process that keeps the tree alive and productive. The harvest, still done entirely by hand using curved axes, takes place in the fierce heat of July and August. Freshly stripped trunks turn a distinctive rust-red that gradually darkens as the bark regrows. Sao Bras de Alportel, the principal town of the eastern interior, was historically the centre of the Algarve's cork trade, and its Museu do Trajo documents the industry alongside the broader material culture of the region. The town sits at 240 metres in a broad valley surrounded by orchards, quieter and cooler than the coast, with a notable Saturday morning market where farmers sell honey, almonds, figs, oranges and medronho.

Monchique, the main settlement of the western serra, is known for three things: the hot springs at Caldas de Monchique, the production of medronho spirit, and the panoramic views from the summit of Foia. The Caldas sit in a steep, wooded valley below the town, where a small spa complex occupies the site of thermal baths used since at least the Roman period. The waters emerge at 32 degrees Celsius, rich in bicarbonate and fluoride, and are prescribed for muscular and digestive complaints. The surrounding forest of eucalyptus, chestnut, cork and pine provides a cool retreat in summer. Medronho production is a cottage industry that persists across the entire serra. The strawberry tree, Arbutus unedo, fruits in late autumn, its berries fermented and then distilled in copper pot stills over wood fires. The resulting spirit, clear and fiery at around 48 per cent alcohol, is offered as a digestif in restaurants across the region and sold from farm gates along the mountain roads.

The eastern interior, centred on the Caldeirao range, is more remote and sparsely populated. Alte, a whitewashed village in the foothills north of Loule, has been somewhat self-consciously preserved as a showcase of traditional Algarvian life, with a spring-fed cascade, a parish church with notable azulejo tiles and craft workshops. Querenca, higher in the hills, clusters around a medieval church and offers views south to the coast on clear days. Further north and east, Alcoutim on the Guadiana river at the northeastern corner of the Algarve is one of the least populated municipalities in Portugal. Its castle faces the Spanish village of Sanlucar de Guadiana across the river, and a zipline now connects the two countries in a crossing that takes roughly 60 seconds at speeds of up to 70 kilometres per hour.

The Via Algarviana, a 300-kilometre long-distance walking trail from Alcoutim to Cabo de Sao Vicente, traverses the full length of the interior and takes roughly two weeks to complete on foot. It follows old drove roads, mule tracks and forest paths through landscapes that have changed little in centuries. Bird life in the serra includes Bonelli's eagle, eagle owl, azure-winged magpie, hoopoe and a range of warblers. Wild boar are common in the cork forests, and the autumn hunting season remains an important part of rural life and local cuisine, with javali (boar) stew appearing on menus from October onwards.

The interior Algarve has experienced steady depopulation since the 1960s, as younger generations moved to the coast or to Lisbon for work. Several villages have permanent populations a fraction of their mid-20th-century peak, and abandoned farmhouses dot the hillsides. More recently, a modest counter-trend has emerged, with foreign buyers restoring ruined quintas and a growing agritourism sector offering accommodation in converted estates. The serra remains the least visited part of the Algarve, which is precisely its appeal. The pace is slow, the air is scented with cistus and pine, and the night skies, free from coastal light pollution, are among the darkest in southern Europe.
