Dique Los Alazanes

Dique Los Alazanes is a small mountain reservoir located at about 1400 meters above sea level, nestled between the Uritorco and Las Gemelas hills, in the heart of the Capilla del Monte mountain range. It is considered the highest dam in the province of Córdoba and one of the highest in Argentina. Its crystal-clear waters, surrounded by rock and mountain vegetation, are fed by the Los Alazanes stream and supply drinking water to the town. There is no vehicular access: the only way to get there is on foot, by horse, or by mule, which has made it one of the most sought-after treks in the area. The route crosses the river several times and goes through mountain landscapes until reaching the water mirror, an ideal place to rest, take photos, and enjoy sport fishing.

A bit of history

The dam was designed and built by the General Directorate of Hydraulics of the province of Córdoba to ensure the supply of drinking water for Capilla del Monte. The works took place in the mid-20th century (sources place its construction between the late 1930s and 1949, with inauguration around 1949), under very difficult conditions: since the site had no vehicle access, a large part of the materials were transported by mule through the mountains. The concrete arch dam is about 25 meters high, and its crest, which serves as a pedestrian bridge, is about 71 meters long. It is mentioned as one of the first arch dams in South America. It is still in operation today, managed by the provincial water resources authorities.

URI's tips

Leave early to make the most of the day and return in daylight. Bring more water than you think you'll need, as the climb is demanding and the sun is strong. Check in at the park ranger's house upon arrival. As it is a mountain trail with no vehicle access and several river crossings, it is highly recommended to hire a certified local guide, especially if you don't know the area. Don't leave trash: everything you bring must come back with you.

What to bring

Comfortable trekking shoes, plenty of water, light food, sunscreen, hat, light jacket depending on the season, and a bag to take your trash back. It is advisable to go with a certified guide.
