The Buracas do Casmilo caves are the centerpiece of this tour. These natural formations are sculpted by erosion over thousands of years, offering a chance to see impressive limestone cavities resulting from the collapse of underground conduits. The caves are free of charge, making this stop both remarkable and accessible.
Adjacent to the caves, the dolina do Casmilo sinkholes reveal the limestone dissolution process that creates these depressions. These water-deposited depressions support local agriculture and grazing, adding a practical dimension to their natural beauty. Both stops offer quick, yet vivid insights into the geology shaping the landscape.

A highlight of the hike is the Outeiro windmill, an old revolving mill that exemplifies the traditional use of wind power to grind cereals. This fragile, wooden structure remains a fascinating testament to ancestral technology. It is situated in a scenic setting, offering a glimpse into historic rural life.
The windmill’s design allows it to rotate in the most favorable direction, demonstrating early ingenuity. Visitors can appreciate the craftsmanship and rustic charm of this crude yet functional artifact nestled among natural surroundings.

The Nossa Senhora do Círculo sanctuary is set atop the mountain, enclosed by a circular stone wall that gives the site its name. From this vantage point, you enjoy breathtaking views of the nearby Buçaco and Caramulo mountains, as well as the Serra da Estrela range.
The sanctuary’s circular layout and elevated position make it a peaceful spot for reflection and photography. It’s a meaningful stop that blends natural beauty with local spirituality, adding depth to the overall experience.
