MUNCYT (Museo Nacional de Ciencia y Tecnología) – formally known as CosmoCaixa – is always a sure hit with the kids, its a science museum, and almost 100% interactive. It is located on the outskirts of the northerly suburb of Alcobendas, just a short bus trip from Plaza Castilla. Here activity rooms show how natures laws work and how matter evolves from atomic structure into the most complex forms of life. Note that to participate in the workshops, Clik, Toca Toca and Planeta Burbuja you need to book in advance and pay separately from the museum entry fee. Last Sunday of the month entrance is free excluding the special activities.
