6000 years ago, human footprints were left in the volcanic mud along the shores of Lake Managua. Preserved over centuries, these footprints can be seen at The Museum of Acahualinca in Managua, the capital of Nicaragua. In addition to the footprints and impressive collections of pre-Colombian artifacts in the city's museums, Managua has much more to offer. The Tiscapa Lagoon Natural Reserve is a watery retreat within the city, with bars, shops, ziplines, and a canopy ride with views of downtown.
