Serras do Socorro e Archeira

Serras do Socorro e Archeira is a protected local landscape near Torres Vedras in Portugal, covering 1,223 hectares of low hills, farmland and small villages. It lies inland, north-west of Lisbon, and suits visitors who would rather walk quiet trails and trace military history than head for the beaches of the Oeste region.

Where is it and what does it include?

The area lies mainly in the parishes of Turcifal and Dois Portos e Runa, and its southern edge meets the municipality of Mafra. Four ranges make it up: Serra do Socorro, Serra da Archeira, Serra da Galharda and Serra do Monte Deixo. These are gentle hills with a patchwork of crops and woodland, not high mountains. The municipality itself describes the landscape as having heritage value without being exceptional on a national scale. Its appeal is calm, proximity to Lisbon, and the mix of nature and history.

Since when is it protected?

The idea of protecting these hills first appeared in 2004. The area was formally established in 2012 and joined the national network of protected areas in 2017. "Protected local landscape" status means it is looked after by the local authority rather than by national bodies.

What is there to see?

The main draw is the remains of the Lines of Torres Vedras, a defensive system built during the Napoleonic wars to protect the Lisbon region. Within the area you will find the Archeira, Feiteira and Catefica forts. You can combine them with a hike across the surrounding hills and see how the engineers of the time used the terrain.

There is also a geological curiosity: a petrified Araucaria trunk from the Late Jurassic, found at Cadriceira. It is a trace of the ancient forests that grew here millions of years ago.

What are the trails like?

Two circular walking routes are open all year:

• the Serra da Archeira trail, about 10 km,
• the Serra do Socorro trail, about 11 km.

Both start at the Heritage and Visitors' Centre. Because the routes are loops, you return to your starting point without arranging transport.
