Barcelona Aquarium
Down at Port Vell, the aquarium's 80-metre glass tunnel walks you under sharks and rays, which is a guaranteed wow for kids. There is a dedicated children's area with interactive exhibits. Go at opening or late afternoon to dodge the midday school crowds, and book online to skip the queue.
CosmoCaixa science museum
The city's science museum is built for curious children, with a recreated flooded Amazon rainforest complete with real animals, a geology wall, and hands-on experiment zones. Easily a half day, and a perfect rainy-afternoon plan. Entry is inexpensive and under-16s often go free.
Gaudi for kids
You do not need a child to love architecture for the Gaudi sites to land. The dragon roof and bone-like balconies of Casa Batllo, and the chimney warriors on the Casa Mila rooftop, look like something from a storybook. Keep visits short and use a family audio guide to hold attention.
Making museums work with children
Pick one museum per day, go early, and bring a snack and water. Many museums have a cafe and most have lifts for strollers. Turning a visit into a hunt, such as spotting five sea creatures or three dragons, keeps younger kids engaged.
Plan B for any weather
Keep one indoor option in your back pocket each day. If the morning beach plan is rained off, the aquarium or CosmoCaixa is an easy, kid-approved switch that still feels like an adventure.
