The Most Beautiful Trails to Run in Portugal This Autumn

Summer may bring the races, the heat, and the long days — but it’s in autumn that trail running in Portugal truly comes alive.
Temperatures drop, the air turns crisp, and the landscapes take on shades of gold and green — a natural invitation to slow down, breathe deeper, and reconnect with the joy of running off the beaten path.

Trail running is more than a sport. It’s a sensory experience — the sound of leaves underfoot, the smell of wet earth, the rhythm of your breathing blending with nature’s silence.
Across Portugal, from the rugged north to the sunny south, you’ll find trails for every runner — challenging, peaceful, and always breathtaking.

Here are five of the most stunning and unforgettable trail destinations in Portugal to explore this autumn. 👇

🌲 1. Serra da Lousã – The Mountain of Endless Trails

In the heart of Portugal, the Serra da Lousã is a paradise for trail runners.
Between schist villages, dense forests, and steep ascents, every route offers the perfect mix of challenge and reward.
You’ll find waterfalls hidden in the trees, technical descents, and some of the best single tracks in the country.

💡 Tip: Try linking the trails between Talasnal, Cerdeira, and Casal Novo — tough climbs, but the views are unforgettable.

🏞️ 2. Peneda-Gerês – The Wild Side of Trail Running

The Peneda-Gerês National Park is one of Portugal’s most majestic — and toughest — running destinations.
Between icy rivers, granite cliffs, and remote mountain villages, every step feels like an adventure back in time.
It’s a place where nature sets the pace — unpredictable, raw, and humbling.

💡 Tip: Perfect for runners who seek elevation, solitude, and the pure essence of mountain running.

🏔️ 3. Serra da Estrela – Where the Air Is Thinner (and the Climbs Longer)

At over 1,900 metres above sea level, Serra da Estrela is the highest mountain in mainland Portugal — and a true endurance test.
The trails are steep and rocky, the weather unpredictable, but the feeling of reaching the summit and gazing at the horizon is pure magic.
Running here is a dialogue between body, mind, and altitude.

💡 Tip: Start from Manteigas for a circular route — one of the best bases for trail running in the region.

🌅 4. Sintra & The Atlantic Coast – Where Green Meets Blue

The Sintra-Cascais Natural Park is a gem for trail runners who crave variety.
From misty forests and stone castles to ocean-view cliffs, every kilometre is an adventure.
Its ever-changing weather makes each run unique — sometimes mystical, sometimes radiant, always unforgettable.

💡 Tip: Try running from Peninha to Adraga Beach at sunrise — golden light, ocean breeze, and silence all in one run.

🌳 5. Serra do Caldeirão – The Algarve Beyond the Coast

Beyond the beaches and resorts, the Serra do Caldeirão reveals the Algarve’s quiet, authentic side.
Rolling hills, cork oak forests, and small villages create the perfect terrain for long, steady runs.
In autumn, the temperatures are mild, the air is clean, and the trails seem to stretch forever.

💡 Tip: Follow sections of the Via Algarviana — a long-distance trail crossing the heart of the Algarve, perfect for solo runs or weekend adventures.

✨ Autumn: The Perfect Terrain

Trail running is, above all, a conversation between body and nature — and autumn is when that dialogue feels most genuine.
With fewer crowds, milder weather, and scenery that changes with every stride, each run becomes an act of connection.

Leave the asphalt behind, chase the wind, and let your legs find their own rhythm.
Because sometimes, the best trails don’t just lead somewhere — they bring you back to yourself.
