A science and technology museum in the university district north of the centre, built around hands-on exhibits and holding what is generally described as South America's largest freshwater aquarium, concentrating on Amazon and Colombian river species. It is aimed squarely at families and school groups and is noisy at weekends. The practical appeal for a visitor is location: it sits beside the Jardin Botanico and the Parque de los Deseos, all within a few minutes of Universidad metro station, so the three make an easy morning.
