Embalse Peñol-Guatapé, is an artificial reservoir located in the Antioquia Department of northwestern Colombia, about two hours east of Medellín. It serves as one of Colombia’s most important hydroelectric power sources, supplying a significant portion of the country’s electricity. Covering approximately 22 square miles and surrounded by rolling green hills, the reservoir was formed by flooding the old town of El Peñol, which was relocated to higher ground. The submerged remains of the old town lie beneath the lake, and a giant cross placed in the water marks its former location. The creation of the lake transformed the region into a scenic and recreational hub, now famous for its winding shoreline dotted with coves, islets, and peninsulas.
The lake is best known for its proximity to the colorful town of Guatapé, famous for its vibrant zócalos—intricately painted baseboards decorating the lower walls of houses—and its lakeside boardwalks, cafes, and boutique shops. One of the most iconic landmarks near the lake is El Peñón de Guatapé a monolithic rock formation that towers over 650 feet above the water. Despite increased development, Guatapé retains a peaceful, small-town feel, especially during weekdays.
