The traveler's view I perfectly remember that moment. I had already covered many kilometers without a single drop of water in my bottle and, yet, in front of us stretched an immense sheet of crystalline water. It was one of those paradoxes that only those who travel by bicycle understand: being surrounded by water and at the same time feeling the thirst becoming more intense. Even so, contemplating the reservoir compensated for some of the fatigue and reminded us that, even on the most complicated days, there is always a landscape capable of bringing back a smile.

Did you know...? Although the dam was completed in 2015, it was the subject of debate for years because the infrastructure needed to fully utilize the stored water took time to develop. In the meantime, the reservoir became a new landscape for the region and an attraction for hikers, cyclists, and nature lovers.

Pay attention to... Unlike other reservoirs located in large open valleys, Siles adapts perfectly to the mountainous terrain of the Sierra de Segura. Its winding shores, surrounded by pine forests, make it look like a natural lake rather than a large engineering work at many points.

The Siles reservoir collects the waters of the Guadalimar River, one of the main tributaries of the Guadalquivir. Its construction began in 2007 and ended in 2015, with the aim of regulating the river's flow, reducing the risk of floods, and ensuring resources for the supply and irrigation of the region. The dam, 52 meters high and 271 meters long, can store 30.5 cubic hectometers of water and is one of the most modern hydraulic infrastructures in the province of Jaén.

This dam was built in 1957 and is filled with the Segura River and the Toba spring, in addition to naturally all the important contributions of water that occur along the channel. The turquoise color of its waters stands out, and that the hydroelectric plant is located, not on the dam wall, but several kilometers downstream, taking advantage of the unevenness of the terrain.
