Why Choose Guadiana?

The Guadiana Valley remains a hidden gem of the Iberian Peninsula, far less visited than the neighbouring Algarve but, thanks to this relative obscurity, the Guadiana Valley is abundant with impressive archeological remains that give the area its timeless quality. Making your way along the route, you’ll encounter the medieval hilltop castle of Castro Marim, the medieval town of Alcoutin, the 12th century Moorish Mosque in the walled town of Mértola and the Roman ruins that are found on the third day of your journey on the way to the charming farming village of Junquiera. Venturing out of the cobbled streets of the historic towns and villages you visit en-route, your trail brings you out among the magical atmosphere of the Guadiana Valley National Park as well as the Castro Marim and Vila Real de Santo António Marsh Natural Reserve – the latter being a popular spot for birdwatchers with sightings of flamingos, spoonbills, avocets and black-winged stilts.

The Path

The Guadiana Valley area is vast plateau over a deep canyon where the river runs; where you follow the backroads through cultivated olive groves, citrus orchards, foothills and tangled forests. Between the many historic towns and villages that you visit on each night of your journey, your route takes you through the Guadiana Valley and along the Spanish border to the coast at Castro Marim. Discover some of Portugal’s most quiet and compelling stretches of natural scenery along the Guadiana River, following old smuggler routes and Roman roads with ample opportunities to stop and take in the landscape before you from the many high-level vantage points stationed along the way. Even in an area as undeveloped and quiet as the National Park, you’ll find good signage and well-maintained paths, although there may be some points at which the tangled forests and undergrowth overrun the paths’ edges. The National Park is noted for its profusion of wild flowers and birdlife, with eagles and buzzards native to the area.

The Accommodation

For your journey we have selected a variety of characterful hotels and B&B’s that complement the areas you visit. From establishments situated on the banks of the river Guadiana to cosy, family-run farmhouses set among the countryside, to us it’s important that the places you return to after a day out exploring Portugal’s many natural and historic wonders are just as much a part of the experience than the walking trail itself. You can expect a buffet breakfast each morning, local produce for dinner, as well as a swimming pool in which to soak up and unwind after a day’s walk. All our hotels on this trip (even in the more rural areas) have free WI-FI, air-conditioning and our hotel in Mértola in particular is a great base from which to explore the local cultural and historical points of interest in the area.
