Best Hiking Trails and Waterfalls in the Algarve

Beyond the Beaches: A Different Algarve

The Algarve that appears in travel magazines — golden cliffs, turquoise water, packed beaches, €15 cocktails — is real and, in season, magnificent. But there is a parallel Algarve that most of its 15 million annual visitors never access: deep valleys where rivers run clear over schist and limestone, clifftop paths with views extending to Morocco on a clear day, and an interior that has barely changed in a generation.

Walking unlocks this version of the region. The trail network is extensive, well-marked, and largely free of charge. What follows is a guide to the best of it.

Rota Vicentina: Europe's Great Coastal Walk

The Rota Vicentina is a network of two interconnected long-distance trails — the Fishermen's Trail (Trilho dos Pescadores, 226km) and the Historical Way (Caminho Histórico, 230km) — running along the wild southwestern coast of Portugal from Santiago do Cacém in the Alentejo to Lagos in the Algarve.

The Fishermen's Trail is the jewel. It follows the coastal cliffs and beaches of the Costa Vicentina, Europe's largest continuous coastal nature reserve, where the land ends in dramatic fashion: sea-sculpted rock arches, beaches accessible only on foot, and viewpoints from which you can watch dolphins in the surf below. The trail passes through Odeceixe, Aljezur, Carrapateira, and Sagres — small towns with enough infrastructure to make multi-day walking comfortable without being overrun.

Walk it section by section (each day's stage is 15–25km) or commit to the full route over 12–15 days. The best months are March, April, October, and November — warm enough to walk comfortably, cool enough to arrive at the day's end without exhaustion.

Pego do Inferno: The Hidden Waterfall Near Tavira

The drive inland from Tavira through the low hills of the eastern Algarve gives little indication of what awaits. The landscape is dry, cork-oak dotted, and unremarkable until the path descends into the Serra do Caldeirão and the sound of water becomes audible. The Pego do Inferno — a natural pool fed year-round by a waterfall dropping from a narrow gorge — is one of the Algarve's best-kept secrets.

The walk from the car park is 40 minutes each way and involves a gentle descent through scrubland. The pool is deepest and clearest in spring; in summer, the flow reduces but the swimming remains possible and the solitude more precious as the coast becomes crowded. The surrounding schist landscape — a world away from the limestone cliffs that define the Algarve's image — rewards slow exploration.

Bordeira Valley: Walk to One of the Finest Beaches in Portugal

The walk from the village of Carrapateira to Praia da Bordeira is one of the best short walks in southern Portugal, and almost entirely unknown outside the surfing community that frequents the beach. The route — approximately 5km each way — descends from the village through a river valley of extraordinary diversity: dunes, migratory shorebirds in autumn and spring, freshwater marsh, and then the beach itself: a kilometre of pale sand backed by red cliffs, with a river entering the sea at one end and surf conditions that bring longboard surfers from across Europe.

The return walk via the clifftop provides entirely different views — the beach from above, the ocean horizon, and the moorland interior of the Vicentina reserve stretching north.

Via Algarviana: The Interior Route

The 300km Via Algarviana runs from Alcoutim, on the Spanish border in the far east, to Cape St. Vincent at the southwestern tip of Portugal — crossing the entire width of the Algarve entirely inland. This is a different region from the coast: the Serra de Monchique, with its volcanic rock and moisture-retaining altitude, supports forests of cork oak, chestnut, and the endemic Portuguese laurel; the Caldeirão hills are covered in cistus and lavender; and the villages along the route are largely untouched by tourism.

Walk it in spring (March to May) when the wildflowers carpet the hillsides in colours that have no equivalent at the coast. The route is waymarked throughout; accommodation is available in small guesthouses and rural tourism properties in most stages.

Practical Information for Hikers

• Maps and navigation: The Rota Vicentina has excellent paper maps and a detailed website with GPX files for each stage. The Via Algarviana is less comprehensively documented; the Alltrails app covers both routes.
• Best season: October to April for the coast; March to May for the interior. Summer hiking in the Algarve is possible but hot — start before 8am and finish by midday.
• Accommodation: The Rota Vicentina has a network of rural guesthouses and agrotourism properties along the route, many bookable through the official website. Advance booking is essential in March–April and October–November.
• Getting there: The nearest airports are Faro (for the eastern Algarve and Via Algarviana) and Faro or Lagos (for the Rota Vicentina). Car hire is recommended for accessing trailheads in the interior.
• Water: Carry at least 2 litres per person in summer; natural water sources are present but require treatment. In winter and spring, stream water is more reliable.
