This artificial reservoir attracts kitesurfers and windsurfers from around the world for its year-round winds. The lake covers the flooded Darién valley of Río Calima, and was built in 1965. Some 86km north of Cali, its temperate climate also attracts caleños looking to cool off on weekends. The green hills that surround the lake are populated with holiday fincas.
Most tourist activity stretches along the northern bank of the lake, from the small town of Darién at the eastern end to the dam to the west. There's no beach; launching points are from grassy slopes that lead down to the water.
Because transportation is infrequent in the area, Lago Calima makes a difficult day trip. You're better off coming for a day or two, especially on the weekend, when the many visitors give the place a party atmosphere.
