Any disoriented traveler might reach Cuesta del Viento and think that he is before the famous Valle de la Luna (valley of the moon) which has been invaded by a huge flood. The tops of the highest peaks hardly outstand through the water, looking like colorful islets lost amidst a sea of turquoise waters. But in fact, this is an artificial lake in the district of Iglesia, created ten years ago by the construction of the Cuesta del Viento dam, which as a result of human intervention, became of the most amazing and unknown sceneries in our country: Cuesta del Viento.
When Cuesta del Viento is reached from San Juan along Route 150, the radiant immensity of a strange valley that combines the aridity of a lunar scenery with the Caribbean transparency of its waters appears before the visitors’ eyes. Inside the lake, surrounded by mountains that reach up to 6,250 meters of height and that reflect a soft violet color on their slopes, solitary islets whose straight walls resemble a submerged fortress stand out. Some of them have strange spiral shapes and others show evidence of a great landslide on one side, caused by the action of the wind and the water.
From a distance, it looks as if this was the ruins of a real Atlantis hiding beneath those spring waters coming down from the mountain heights. And in the background, on the other side of the lake, some reddish gales of sand rise to the sky with their threatening whirlwinds.
