Several Madrid museums are free every day, and the big ones open for free on set afternoons or mornings, with kids often free anyway. That makes a rainy day cheap. Here's what we checked, from a hangar of real planes to the free last hours at the Prado.
About 200 aircraft fill seven hangars and a large outdoor field beside the Cuatro Vientos airfield. Kids walk past early wood-and-canvas flying machines, seaplanes, fighter jets, trainers and helicopters, with the outdoor field split into zones by type. A café and a gift shop sit by the outdoor display.
A 19-meter-tall hall under a stained-glass ceiling, ringed by wrought-iron balconies and spiral staircases, with 5,800 minerals and more than 12,000 fossils on display. Kids spot meteorites, gemstones, crystals from every Spanish region, and fossil animals and plants going back to the Precambrian. An elevator also reaches the upper galleries.
Spain's national science and technology museum. In the round Gabinete hall, 19th-century lab instruments sit next to more than 90 hands-on modules where kids test sound, light, magnetism, and motion. The Patrimonio hall runs from early microscopes and zoetropes to old TVs and phones, the first bicycles, cars, and motorcycles.
Eight centuries of Spanish seafaring fill the galleries inside the Navy headquarters: rooms of detailed ship models from galleons to steamships, naval weapons, navigation instruments and explorers' maps. The star piece is Juan de la Cosa's chart from 1500, the oldest surviving map to show the Americas. Storytelling sessions, theatrical tours with costumed historical figures and ship-model workshops run for families through the year.
Exhibitions on technology, art, and science inside the Telefónica building on Gran Vía, the city's first skyscraper. The permanent show, Exponencial, follows the leap from the first telephones to mobile phones, the internet, and AI. Temporary shows change through the year, and Sunday family workshops tie into them.
The Museo Tiflológico is ONCE's museum for seeing and touching. Its biggest draw for kids is a hall of scale models of famous monuments from Spain and around the world, made to be explored with the hands, with free audio guides. Other rooms hold art by blind and low-vision artists and old braille machines and writing tools. Signs come in braille and large print.
Spain's first public planetarium sits in Tierno Galván park and reopened in 2026 after a year and a half of renovation. Its new dome projector puts 10 million stars overhead and plays full-dome 4K films. Weekend mornings bring films made for kids, including El cielo de Cloe, a sing-along sky lesson for preschoolers. The halls on the moon, eclipses and European space missions are free to walk.
The national museum of the Americas, with pre-Columbian gold, Inca textiles, and a 2,000-year-old Paracas mummy bundle from Peru, still wearing its gold nose ornament and collar. Rooms move through explorers' maps, daily life, religion, and writing. Look for the Tro-Cortesiano Codex, a painted Maya book, and the gold of the Quimbaya Treasure.
Spain's national archaeology museum runs from prehistory to the Middle Ages across several floors. Kids head for the Egyptian rooms, with real mummies and painted coffins, and for Iberian stone sculptures like the Dama de Elche. Saturday family programs add theater, storytelling, the sounds of the ancient world and hands-on visit-workshops where kids try the trades of the past.
Spain's national art museum holds Velázquez's Las Meninas, Bosch's Garden of Earthly Delights and Goya's Saturn. For kids, the Prado's own children's itinerary follows Infanta Margarita, the girl at the center of Las Meninas, and her friends through nine paintings, with free audio and short videos on the museum website. Holiday weekends add family workshops in the galleries.
