In recent years, Portugal has become a true paradise for those who enjoy walking on wooden boardwalks. From north to south, dozens of routes now wind through mountains, rivers, lagoons and cliffs — some just a few hundred metres long, others stretching for several kilometres. In this guide, we've put together the ranking of the 10 longest walkways in Portugal, ordered by distance. Each entry includes location, difficulty and what makes the route unique, to help you choose your next adventure.
How We Measured Length
Before diving into the ranking, an important note: measuring a walkway's length isn't always straightforward. Some routes are entirely made of wooden boardwalks; others combine elevated sections with dirt paths, bridges and stairways. Wherever possible, we list the total length of the official linear route, even when it includes non-elevated sections. Where sources disagree, we've chosen the most consensual figure.

Honourable Mentions
A few walkways came close to the top 10 and are equally worth exploring:
- Passadiços de Alvor (Portimão) — about 4.5 km between the estuary, salt marshes and dunes.
- Passadiço Manta Rota (Vila Real de Santo António) — approximately 4 km along the dune system.
- Passadiços do Rio Homem (Terras de Bouro) — part of a planned 20 km ecovia along the River Homem, in the Gerês. Some sections are already open, but construction is ongoing.

Which Walkway Should You Choose?
If you're after the biggest challenge, the Passadiços do Mondego and Paiva are unbeatable — both have significant elevation and physical demand. For an easy family walk, go for the Rio Uíma, Barrinha de Esmoriz or Salgados walkways. If you want to combine beach and walking, Manta Rota, Alvor and Coura are obvious picks.
A tip: plan these walks across different seasons. In summer, coastal walkways come alive; in spring, mountains and wetlands are in full bloom; in autumn, forest routes (Paiva, Uíma, Corgo) become spectacular with warm colours.
Frequently Asked Questions
What is the longest walkway in Portugal?
The Passadiços de Sistelo, in Arcos de Valdevez — part of the Ecovia do Vez — are Portugal's longest walkway, stretching about 33 kilometres along the Vez and Lima Rivers.
Are the Passadiços do Paiva paid?
Yes, the Passadiços do Paiva require a ticket and prior booking. Most of the other walkways on this list have free access.
Which walkways are easiest for families?
The Rio Uíma (Santa Maria da Feira), Barrinha de Esmoriz (Ovar), Salgados (Albufeira) and Manta Rota (Algarve) walkways are all flat and suitable for children.
Can I do all of them in one weekend?
No. Most of these walkways require a full morning or afternoon. The ideal is to plan a regional route — for example, combining Paiva and Uíma in the North, or Salgados, Alvor and Manta Rota in the Algarve.
When is the best time to walk them?
Spring and autumn are generally the best seasons: mild temperatures and vegetation in good condition. In summer, prefer coastal walkways; in winter, avoid mountain routes such as the Mondego due to the risk of ice.
Conclusion
Portugal now has one of the most complete networks of walkways in Europe. From Sistelo to Vizela, from the Mondego to the Lagoa dos Salgados, each route reveals a different side of the country — mountains, rivers, lagoons, dunes and rural villages, all accessible through wooden structures that protect ecosystems and democratise access to nature.
