Portugal is much more than popular beaches and historic cities. Across the country, you’ll find natural treasures that combine unspoilt scenery, biodiversity and cultural heritage.
Many of these places are still off the usual tourist trail, which makes them a good choice for anyone looking for more authentic experiences. It works just as well for a weekend break as it does for a longer holiday, with options to suit different tastes.
Here, you’ll discover natural destinations in Portugal that are genuinely worth visiting — or seeing again with a fresh perspective.
Passadiços do Paiva: one of the most beautiful trails
Located in Arouca, the Passadiços do Paiva have become a standout example of nature tourism. The route stretches for around 8 km along the Paiva River and has already received international tourism awards, including the World Travel Awards.
The trail is accessible, clearly signposted and well-suited to anyone wanting an immersive experience without major technical difficulty. Along the way, there are views over the river, river beaches and the famous 516 Arouca Bridge, one of the longest pedestrian suspension bridges in the world, measuring 516 metres.

Praia da Ursa: one of Portugal’s wildest beaches
Close to Cabo da Roca in Sintra, Praia da Ursa is recognised for its imposing rock formations and its almost untouched setting.
There are no lifeguards, beach bars or facilities, which helps preserve its natural character but also means visitors need to take extra care. The Sintra Municipal Council has, on several occasions, advised against going down to or staying on the beach due to the risk of falling rocks and unstable cliffs, particularly during bad weather or rough seas.
The good news is that there’s no need to make the descent. The view from the top of the cliffs is wide and impressive, allowing you to take in the beach safely from the trails near Cabo da Roca.
Algar de Benagil: an iconic sea cave in the Algarve
The Algar de Benagil in the Algarve has become one of Portugal’s most shared images in recent years, especially on social media and Google Discover. Located in Lagoa, the cave, which is only accessible by sea, stands out for its open ceiling that lets natural light pour in.
It’s a clear example of how nature tourism in Portugal can combine striking scenery with international popularity.
How to visit Algar de Benagil
- Kayak or paddleboard from Benagil Beach
- An authorised boat tour
- Never attempt to swim there on days when the sea is rough
The best time to go is outside the peak summer season, when there are fewer boats.

Montesinho: magic in Trás-os-Montes
The Montesinho Natural Park, in Trás-os-Montes, is one of the largest protected areas in the country, covering around 75,000 hectares, according to ICNF data. In contrast to more heavily visited destinations, this is a place of silence, unspoilt landscapes and schist villages that feel almost frozen in time.
This natural park is one of the best options for anyone seeking nature tourism in inland Portugal, away from the crowds. Biodiversity is one of its main highlights: Montesinho is home to species such as the Iberian wolf and the golden eagle.
What you can do in Montesinho
- Walk along marked hiking trails
- Visit villages such as Rio de Onor, known for its traditional communal organisation
- Go birdwatching and observe local wildlife
- Try traditional Trás-os-Montes cuisine
For those looking into lesser-known natural destinations in Portugal, Montesinho stands out as a strong and authentic choice.
Serra do Açor: secret lagoons and schist villages
Located in the Central region, between Arganil and Pampilhosa da Serra, the Serra do Açor is a genuine green refuge. It forms part of the Natura 2000 Network and includes the Mata da Margaraça, one of the rare near-intact forests in mainland Portugal.
This is where you’ll find the well-known Fraga da Pena, a waterfall around 20 metres high that draws visitors during the warmer months. The area is also associated with historic villages such as Piódão, which, despite its growing profile, remains set within striking natural surroundings.
