A masterpiece carefully guarded by nature. On the border between the territories of Bonarcado and Santu Lussurgiu, along Provincial Road 15, which connects the two picturesque villages of Montiferru, lies an enchanting landscape, which you will discover little by little. You'll start to hear the quiet roar of the water from the clearing by the roadside, the starting point of the path that will lead you to the valley and the waterfall of sos Molinos. This downhill mule track, with the occasional remnant of a paving stone, is lined with holm oaks, downy oaks and alders, which will accompany you on your walk. Along with the trees, you'll see countless laurel bushes, so lush that the valley has been declared a special area of conservation. Besides the green of the Mediterranean vegetation, you will be struck by the variety of flowers around the pond formed below the waterfall: cyclamens, daisies and orchids add pops of colour to the magical scenery of the water cascading over 30 metres, jumping from rock to rock.
