Portugal doesn’t do national parks in the same way as Spain or Italy. Instead, most protected areas fall under the natural park label. Portugal's best natural parks feature dramatic scenery, wildlife, and plenty of space to roam, just with more villages and working landscapes folded in.
Peneda‑Gerês National Park
Peneda‑Gerês sits right up in the north, pressed against the Spanish border, and feels wilder than anywhere else in mainland Portugal. Granite mountains, dense oak forests, and scattered stone villages give it a slightly untamed edge. It’s quieter than you’d expect for the country’s only national park, particularly midweek.
Top thing to do: spend a day walking one of the old Roman routes or forest trails, stopping for river swims along the way when the weather allows.
Main highlight: the Mata de Albergaria woodland, where ancient trees, mossy stones, and the Roman Geira road all come together.
Serra da Estrela Natural Park
Serra da Estrela feels like Portugal turning the volume down and the altitude up. This is the country’s highest mountain range, with broad valleys, bare rock plateaus, and weather that can change quickly. Villages are spread out and practical rather than pretty, shaped by cold winters and isolation.
Top thing to do: take on one of the longer mountain walks between villages, where distances are big, and views stay open for miles.
Main highlight: the glacial valley around Covão d’Ametade, especially outside peak summer when it’s calmer.
Douro International Natural Park
Douro Internacional runs along the border with Spain, where the river cuts deep into the landscape and vineyards cling to steep, dry slopes. The terrain is rugged and sparsely populated, with small villages that feel properly remote and closely tied to farming and wine production. Wildlife is a big part of the experience too, especially birds circling above the canyon walls, and it remains one of the least visited parks on this list.
Top thing to do: join a slow boat trip on the Douro to see the scale of the river gorge from below.
Highlight: the viewpoints near Miranda do Douro, where the river bends sharply through the cliffs.
Arrábida Natural Park
Arrábida is compact but dramatic, tucked between Lisbon and Setúbal with steep hills dropping straight into the sea. The colours are softer than the Algarve, with pale cliffs, green slopes, and clear water that changes with the light. It feels close to the city yet oddly removed once you’re inside the park. You notice the contrast between busy roads nearby and how quiet it gets on the trails.
Top thing to do: walk one of the coastal paths that link viewpoints above the sea, ideally early in the day.
Highlight: Convento da Arrábida, perched high above the coastline with wide views across the park and ocean.
Sudoeste Alentejano e Costa Vicentina Natural Park
This stretch of coast runs long and loose, with cliffs, empty beaches, and small towns that still revolve around fishing. The landscape feels open and exposed, shaped by wind and Atlantic weather rather than tourism. Development is limited, so distances feel bigger and services thinner than elsewhere.
Top thing to do: follow a section of the Rota Vicentina along the clifftops, where the walking is straightforward but the scenery keeps changing.
Highlight: Cabo Sardão, where sheer cliffs and nesting storks give the coast a raw, elemental feel.
Ria Formosa Natural Park
Ria Formosa is a low‑lying world of lagoons, islands, and shifting sandbanks along the Algarve coast. Instead of cliffs, you get flat horizons, calm water, and a slower rhythm tied to tides and boats. Towns like Olhão and Faro sit right next to the park, so nature and everyday life overlap constantly. It’s gentler and more subtle than most people expect from the Algarve.
Top thing to do: take a boat out to one of the barrier islands and wander on foot once you arrive.
Highlight: Ilha Deserta, where the sense of space and quiet feels far removed from the mainland.
