The 3 must-do indoor plans
If you only have time for one indoor plan, pick Cosmocaixa, the science museum that handles 4 hours of curiosity for ages 0 to 13. The flooded Amazon hall, the Geological Wall and the under-6 Bub.Bub Bosc area cover every age. L’Aquarium with the 80-meter shark tunnel works for any kid age and is fully indoor. The Museu de la Xocolata at El Born includes a chocolate workshop on weekends and a chocolate sample at the entrance.
Free or cheap indoor plans
CaixaForum has free entry on weekends and free family workshops. The MACBA contemporary art museum is free first Sunday of the month. The Museu Maritim has the original Royal Galley replica and is included in the Barcelona Card. The Mercat de Sant Antoni library on Sundays opens a kids reading room. The Catedral cloister has 13 white geese that fascinate small kids and entry is free outside service hours.
Tibidabo indoor and IMAX
Tibidabo Mountain has a hidden gem: the upper indoor pavilion has the 1928 carousel, the Aerial Sky Walk simulator and 3 calm rides under cover. Pay only the basic Camí del Cel ticket if you want only the indoor area (10 euros). The IMAX Port Vell shows kids documentaries about wildlife and space, perfect 1-hour rainy plan. The Phenomena cinema in Eixample replays family classics in original version every weekend.
Magic Fountain show with kids
The Magic Fountain show runs Friday and Saturday from 9 pm October to April and Wednesday to Sunday from 9:30 pm May to September. The MNAC steps are partially covered and let you watch the show without getting soaked. Plan to arrive 45 minutes ahead with kids to find a covered spot. Combine with dinner at one of the restaurants on Avenida Maria Cristina before the show starts.
