The Loriga Glacial Valley is an impressive geological formation of glacial origin, approximately 6.5 kilometers long, located in the municipality of Seia, right in the Serra da Estrela Natural Park. Shaped during the last ice age, this "U"-shaped valley stands out for its steep granite slopes, staircase-like cirques, and the famous village of Loriga, often nicknamed the "Portuguese Switzerland" due to its mountainous surroundings.👍🥾

Among the terraces, chestnut groves and pine forests, a rural heritage that is as authentic as it is surprising is hidden. Like this house, for example, which seems to have grown out of the rock itself: embedded in a huge boulder, in a perfect symbiosis between popular architecture and raw nature. It is as if it had been sculpted by the mountain.

As the name suggests, this is a large hollow, an amphitheater sculpted by nature, where a lagoon lies that, on hot summer days, can disappear completely. Even so, the landscape remains stunning, imposing and filled with the overwhelming silence of the mountain.

At the Covão do Meio Reservoir, the waters give the illusion of floating on the horizon: a serene mirror suspended between the sky and the mountains. But the most surprising thing is the tunnel, over two kilometres long, that drains the excess water to Lagoa Comprida, in a piece of engineering that is invisible to the eye.

In Loriga, human ingenuity has shaped the mountain. Over the centuries, persistent hands have built terraces and designed an intricate irrigation network, transforming a once rocky valley into an oasis of fertility. More than a legacy, it is a living testament to the wisdom and resilience of the people of Loriga, a true landmark that honors the past and enriches the present.

Beautiful panoramic views from the highest point in Portugal. You can ski here in winter, and there is sometimes snow even in summer.

Beautiful waterfall, but potentially empty. There is access via the levada from Cabeça, with a flat path in relatively good condition. People with vertigo may pass through the canal in the narrowest areas. Wear trousers and boots because of the nettles. Enjoy!!!
