Tucked away in the heart of the Pyrenees mountains, the Barrage Cap de Long is a breathtakingly beautiful reservoir that combines natural wonder with human engineering. Located in the Hautes-Pyrénées department in southwestern France, this alpine dam isn’t just a vital source of hydroelectric power—it’s also a destination that captivates nature lovers, hikers, photographers, and travelers seeking tranquility off the beaten path.

In this article, we’ll explore the history, geography, travel tips, and things to do around Barrage Cap de Long, and why it’s becoming one of the most talked-about places for adventurous spirits.

What is Barrage Cap de Long?

The Barrage Cap de Long is a massive hydroelectric dam built between 1946 and 1953 in the Néouvielle massif, part of the larger Pyrenees mountain range. It was created by damming the valley to store water from glacial sources and mountain streams. The result is a spectacular lake at an altitude of over 2,100 meters (6,890 feet), making it one of the highest large dams in France.

With a capacity of more than 65 million cubic meters of water and a length of 1.5 kilometers, this reservoir plays a crucial role in regional energy production. But beyond its industrial function, Cap de Long has evolved into a unique destination where engineering marvel meets untouched wilderness.

How to Get to Barrage Cap de Long

Reaching Barrage Cap de Long is an adventure in itself. Most travelers begin their journey in the nearby town of Saint-Lary-Soulan, which offers charming accommodations, local eateries, and essential services. From there, it’s about a 30-kilometer (18-mile) drive along winding mountain roads through the stunning Aure Valley.

Important Tip: The road to the dam is seasonal—typically open from late spring to early autumn. It’s always recommended to check local access conditions before planning your trip, as weather can quickly change in the mountains.
