Havana isn’t really tailored for travel with children (there are no theme parks, shopping malls, cinemas or McDonalds!) but there are plenty of interesting places to visit and sites to see. Kids particularly enjoy:

- live music in the restaurants and cafes

- tanks, planes and "real bullet marks" at the Museo de la Revolucion

- looking at the sometimes bizarre art & sculptures at the Palacio de Bellas Artes

- watching the sea crash up over on the Malecon

- exploring the Castillo de la Real Fuera 

- the pool on top of the Parque Central hotel
