Living in Barcelona means we’re always looking for new family plans in a city we already know well. So when Big Fun Museum invited us to visit, we turned it into a Sunday with the kids — a family of four, with two boys aged 12 and 9.
It turned out to be one of those rare plans where nobody is bored and everyone is involved. Below is what’s actually inside, what it costs, and the honest answer on whether it’s worth it — because the pricing has one catch that families need to know about before they turn up.
Where to stay in Barcelona — our three picks
Budget · Gràcia Generator Barcelona – private family rooms at hostel prices, five minutes from Passeig de Gràcia and metro Diagonal (L3/L5). Rooms are small and the bar downstairs is lively, so ask for a higher floor.
Mid-range · Via Laietana H10 Cubik – on the edge of the Gothic Quarter, with the Atic rooftop terrace and pool. You can walk to the cathedral, the beach and the Born from the door, which saves you metro tickets all week.
Luxury · Eixample The Cotton House Hotel, Autograph Collection – the old cotton guild building on Gran Via, a ten-minute walk from Casa Batlló and the Sagrada Família side of Eixample. Quiet, grown-up, and the rooftop is the reason to book it.

What Big Fun Museum Barcelona is
An interactive, immersive museum in the very centre of Barcelona, on La Rambla a few minutes from Plaça de Catalunya. It’s the opposite of a classic museum: touching, posing and interacting aren’t just allowed, they’re the entire point.
Every room is built to play with perspective and deliver that “wait — how is this possible?” moment. Upside-down rooms, oversized objects, optical illusions, colourful installations designed to be photographed.
Our family experience
From the first room, both boys were fully engaged. Our 12-year-old went straight for the optical illusions and the more technical setups, working out how each one was built. Our 9-year-old couldn’t stop exploring every corner and kept asking to do rooms again.
And honestly, we were just as involved — laughing, posing, taking far too many photos. We spent over two hours inside and the time went quickly.
It’s genuinely rare to find an activity where a 9-year-old, a 12-year-old and two adults are all entertained by the same thing at the same time.

Here’s the thing nobody tells you: there is no child ticket. Children under 5 go free, and from 5 upwards everyone pays the full adult price. A nine-year-old costs exactly what an adult costs.
That matters for planning. A family of two adults and two school-age children is €100 at the door, or €90 booked online — not the €60-ish you’d assume from most Barcelona attractions, where children usually pay around half.
So: book online. It saves €2.50 a head, which on a family of four is €10. And if you live here, the resident discount is worth more than any promotion they run.

Is it worth it?
For us, yes — but the price changes who it’s for.
At €22.50 a head with no child rate, this is not a cheap hour. What it buys is a plan that works across a wide age range at once, which is harder to find than it sounds, and a few hundred photos your kids will actually want to look at afterwards.
Worth it if: you have children roughly 7 and up, especially a mixed-age group or teenagers; it’s raining; or you’re looking for something different from another Gaudí building.
Skip it if: your children are under 5 (free, but they won’t get the illusions), or you’re on a tight budget in a city where the Museu Blau is free on Sunday afternoons and Park Güell’s forest costs nothing.
A rainy-day plan in central Barcelona
Barcelona in the rain catches a lot of families out — most of what people come for is outdoors. Big Fun Museum is a solid wet-afternoon answer because it’s central, indoors and takes two hours.
Pair it with one of these and you have a full day without getting soaked:
CosmoCaixa — the science museum, and the best rainy-day option in the city
The Chocolate Museum — small, indoors, in El Born, and your ticket is a bar of chocolate
Museu Blau — natural history, and free every Sunday after 3pm
