In a remote area of Portugal's Peneda-Gerês National Park, the Sobroso River has formed a natural attraction known as the Seven Lagoons ('Poços Verdes do Sobroso'). Access to the lagoons requires a hike, which begins in the small granite village of Xertelo. This tour offers a guided trek into the mountainous landscape to reach the lagoons.

The Trail to the Lagoons
The hike follows the path of a historic 'levada,' a man-made water channel used for irrigation. This trail provides a way to experience the engineering of the local people who have inhabited these mountains for generations. As the trail ascends, the scenery changes, offering views of the surrounding landscape. The air is scented with pine and wild heather, and the primary sounds are the wind and the nearby water.

Historical Structures Along the Way
Along the trail, hikers will pass the Fojo do Lobo de Xertelo, a historical wolf trap. This structure consists of converging stone walls that were built to funnel wolves into a deep pit. It serves as a monument to the historical relationship between humans and wildlife in this region and the challenges of co-existence.
Upon arrival, the river opens into a series of cascading pools. The Seven Lagoons are known for their brilliant turquoise water, which is filtered by the granite and is exceptionally clear. Small waterfalls connect the pools, creating a scenic and tranquil environment. The lagoons are suitable for swimming, offering a refreshing experience in a natural setting.

This hike is more than just a walk to a scenic spot; it is an immersion in a UNESCO World Biosphere Reserve, an area recognized for its ecological importance. The journey connects you to the history of the land and its people, offering a direct experience of the preserved natural environment in this part of the world.
