Buenos Aires has two toy museums. One is this one that is located in Greater Buenos Aires, in Boulogne, where you can see an interesting collection of toys from different periods and it stands out for the activities and workshops for children that are held on weekends. So if you are visiting the city with your children, it may be a good idea to take them there. One of the ones we enjoy the most is the kite workshop. You can check the agenda on the museum's website.
A museum not very well known but that has all the toys that we all used in our childhood in Argentina. The ticket has a value of 15 pesos (1 dollar). On weekends there are a series of activities for the youngest with teachers where they can play those old games themselves.
