Both Piódão and Foz d'Égua are accessible by car. But it's worth hiking the trail that connects them. It takes about 45 minutes, downhill from Piódão to Foz d'Égua (remember that the return is a slight climb). It's worth crossing the restored suspension bridge in Foz d'Égua before returning to Piódão. The Foz d'Égua pool is a popular spot for a dip in its very cold waters. Dipping your feet in the icy water of the stream is always very pleasant after a hike, immersing yourself in nature. I did it and recommend it. 👍🥾

The hallmark of this mountain village with its narrow, winding streets is slate. This material, abundant in the region, is used in the construction of both the houses and the streets, giving rise to the town's characteristic color, interrupted only occasionally by the vibrant blue of the windows and doors of some houses.

The church stands out in the village due to its contrast with the traditional houses. The interior altar is carved from gilded wood, and the walls are tiled. The mother church, dedicated to the Immaculate Conception, stands out from the small, two-story houses. Completely whitewashed and with its unique cylindrical buttresses, it was built by the locals in the 19th century using their own financial resources.

Piódão is a particularly well-preserved, historic village worth a visit. If you're looking for peace and quiet and enjoy hiking, you've come to the right place. Although the historic village of Piódão doesn't hold any particular significance in Portugal's history, it has recently become an increasingly popular tourist attraction, perhaps due to its beautiful location in the Serra do Açor.

It's not really a parking lot; parking is free along the street, but on some days it's hard to find a spot.
