The Miami Children’s Museum offers a dynamic, hands-on experience for kids. Visitors of all ages will love the interactive and bilingual activities and crafts throughout the museum. Discover a two-story sandcastle, board a life-size cruise ship or explore the kid-size veterinary clinic, television studio, or health and wellness center. Free Day for everyone is the third Friday of each month from 3 to 9 p.m. The museum is always free for infants under one year old.
