A former prison, the Children's Museum was converted into an educational monument after Costa Rica's military was abolished in 1949. It is a large yellow building with high walls, corner turrets and it looks like a cartoonish old castle. There are over 32 exhibition rooms and numerous activities and experiences for all ages to take part in, indoors and out, with a focus on music culture, and science. Within its walls you can visit an old milk farm, learn the history of Costa Rica, and make melodies by dancing. Adults and children can enjoy spending hours exploring the museum's multiple exhibits. Take a taxi to the Museo de Los Ninos, on the outskirts of San Jose's red light district,
It is open Monday through Friday from 8:00 am to 4:00 pm and on Saturday and Sunday from 10:00 am to 5:00 pm. It costs $5 for adults, less for children, depending on age.
