Laguna de Fúquene, Sacred lake in Cundinamarca Department, Colombia.

Laguna de Fúquene is a heart-shaped freshwater lake on the border of Cundinamarca and Boyacá, in the Ubaté-Chiquinquirá Valley at 2,540 m. It has numerous islands, one of them a former Muisca sanctuary, and is fed by the Ubaté River and drained by the Suárez. Its surface fell from about 100 km² in 1934 to roughly 30 km².

The lake was originally much larger and deeper before Europeans arrived in the 16th century. Since then, drainage, land use changes, and environmental shifts have gradually reduced its size.

In the Chibcha language of the Muisca, Fúquene means "Place of swamps covered with fog", "Bed of the fox" or "Holy People", after the rituals held there. The lake was a ritual site linking the zipa in the south with the zaque in the north, and merchants crossed it between the two halves of the Muisca Confederation. Today basket-weaving artisans and fishing families around the shore still depend on the lake.

The area has several access points from the surrounding towns, with Ubaté, Chiquinquirá, and Simijaca being the main gateways. Visitors should bring weather-appropriate clothing, as mist and humidity are common at this elevation.

The water surface and bird populations have shrunk dramatically in recent decades, reflecting the ecological changes of the place. A visitor can observe these shifts in the altered shorelines and the less diverse wildlife seen today.
