Barcelona – Big Fun Museum & Museum of Illusions Experience

Barcelona’s Big Fun Museum turns sightseeing into a giant photo set, while the nearby Museum of Illusions makes your eyes argue with your brain. You can step into an upside-down room, pose beside giant objects, jump into a ball pit, and appear inside 3D artwork.

I like the wide mix of rooms, since families, couples, teenagers, and adults looking for a break from churches and galleries all find something to do. I also like the combined ticket, which gives you two different kinds of playful entertainment for $35 and lets you take pictures throughout.

The main consideration is that the experience is aimed more at fun than serious museum content. Some displays may need repair, and parts of the Museum of Illusions can feel more like paintings on walls than interactive exhibits.

Key points to know before you go

• Nine fantasy rooms at Big Fun: Expect giant objects, a sweet-themed room, Alice-inspired scenes, food art, and more.
• Upside-down photo opportunities: The Topsy-Turvy setting rewards careful positioning and a willing photographer.
• A separate Museum of Illusions: This focuses on 3D-effect paintings, forced perspective, and visual tricks.
• Good for mixed-age groups: Children get active play, while adults and couples get plenty of amusing photo setups.
• Two museums close together: You can visit both without arranging transport between them.
• Allow time for photographs: You may need to wait for another group to finish at the most popular scenes.

Why this combo works in Barcelona

Barcelona has no shortage of grand architecture, art museums, and historic sights. That is part of its appeal, but after a morning of churches and formal galleries, a playful stop can reset the mood. This ticket gives you a light, social activity where the point is not to study quietly but to take part.

The Big Fun Museum is the larger and more varied half. Its nine themed rooms change the setting every few minutes, so you are unlikely to feel stuck in one display for long. The Museum of Illusions is more focused. It uses wall paintings, perspective tricks, and 3D effects to make you part of the scene.

At $35 per person, the ticket is not a bargain if you rush through both buildings. It makes better financial sense when you have enough time to pose for pictures, try several angles, and enjoy the exhibits with family or friends. A combined admission also saves you from choosing one attraction and missing the other.

Starting at the Big Fun Museum on Rambla de Sant Josep

Your entry point is the museum entrance on Rambla de Sant Josep. Show your voucher at the door, then begin with the Big Fun Museum. Transportation and a guide are not included, so you make your own way there and explore independently.

That self-guided format suits this attraction. Each room presents a simple visual idea, and you can move at your own pace. You do not need a guide explaining a collection or keeping a group together. Instead, your companion often becomes part of the activity by taking pictures and helping you find the right position.

The Big Fun Museum is particularly easy for groups because the rooms create natural roles. One person poses, one takes the picture, and everyone else suggests a more ridiculous version. Lockers have been available, which helps when you do not want to carry bags through every display.

Giant’s House and the Upside Down House

The Giant’s House plays with scale. Oversized objects make you appear very small, giving you an instant story for a photograph. This is simple but effective, especially for children who enjoy pretending that an ordinary room has been taken over by giants.

Next comes the Upside Down House, also described as the Topsy-Turvy Museum. The room asks you to navigate a world that appears to have been turned over. The best pictures depend on standing in the correct spot and tilting the camera or framing the scene carefully.

You will get more from these rooms if you slow down for a few seconds. Do not simply walk in, snap one picture, and leave. Try different poses and let the person taking the picture step back far enough to include the full room. The attraction works best when everyone accepts that the photo setup is part of the activity.

Sweet Museum and Alice Through the Looking Glass

The Sweet Museum brings a bright, dessert-themed change of mood. It is designed to look playful rather than realistic, with scenes built around treats and an oversized sense of fun. If you are visiting with children, this is likely to be one of the easiest rooms for them to understand and enjoy.

The Alice Through the Looking Glass section continues the fantasy theme. It gives you another chance to pose inside an altered world, with the familiar idea of entering a storybook setting. This part is less about learning the story and more about creating a picture that makes the room look strange or dreamlike.

These two rooms help explain why the Big Fun Museum suits birthdays and family outings. One visitor used the displays for birthday pictures, including a scene involving a huge cake and another with a large bottle of wine. You can use the same setups for a celebration, a couple’s outing, or simply a group picture that is more playful than a standard city souvenir.

Believe It or Not and the Food Art room

The Believe It or Not room turns its attention to unusual real-world records and oddities. The information provided does not give a full list of the exhibits, so you should treat it as a visual curiosity room rather than a detailed record-breaking museum.

Food Art is one of the more unusual concepts in the building. It recreates well-known works of art using food as the material. The result is visually amusing and may leave you thinking about lunch, especially if you have been walking around Barcelona for hours.

This room is worth taking at a measured pace because the joke is in recognizing the artwork and then noticing how it has been rebuilt. It is not a traditional art display, and you should not expect original masterpieces. Instead, it offers a playful bridge between familiar art and everyday objects.

Museum of Madness and the Magic Room

The Museum of Madness takes a darker turn. It presents a walkthrough exhibition about brutal psychiatric treatments in history. This section may feel out of place beside sweets, giant rooms, and cartoon-like fantasy scenes, so consider your group before entering.

The subject matter is more unsettling than the rest of the Big Fun Museum. It may appeal to adults interested in difficult medical history, but younger children could find it uncomfortable. The supplied information does not specify age restrictions, so use your own judgment about whether it fits your family.

The Magic Room finishes the Big Fun Museum with a digital experience. You can explore a magical forest, look at stars, and enjoy views of Barcelona through a changing visual setting. It provides a calmer final note after the more active rooms, although the exact digital effects may vary.

Together, these rooms give the Big Fun Museum its range. You move from scale tricks to sweets, fantasy, records, food-based art, disturbing history, and digital scenes. That variety is a strength, though it also means the quality and polish may not feel identical in every room.

What the Museum of Illusions adds

The Museum of Illusions is in a separate building close to the Big Fun Museum. You do not need transport between the two, which makes the combo easy to fit into a day of walking around central Barcelona.

This museum centers on 3D-effect paintings and perspective tricks. Instead of entering several full fantasy rooms, you stand in front of painted scenes and become part of the image. The museum’s strongest feature is the chance to create photographs that look impossible when the camera is placed correctly.

Pay attention to floor spots or marked positions. They show you where to stand so the perspective works. If you ignore them, the image may look flat or strangely proportioned. The attraction becomes much more successful when you follow the intended viewpoint.

You may need to wait for another group to finish at a popular artwork. That is normal for a photo-based museum, where each display takes longer than a conventional painting. The wait is usually manageable when the building is not crowded, but a busy visit can slow your progress.

The two museums also differ in style. The Big Fun Museum gives you rooms and props to explore. The Museum of Illusions gives you paintings and camera angles to test. If you prefer interactive scenes, the first building may be your favorite. If you enjoy clever perspective photography, the second may be the stronger half.

Who will enjoy it most

I would recommend this ticket first to families with school-age children, teenagers, couples, and groups of adults who want a playful hour or two. It is also useful when your group has mixed interests. One person can enjoy the visual art jokes, another can focus on photography, and children can take part without needing a long explanation.

Adults should not dismiss it as only a children’s attraction. One booking party with an 18-year-old daughter enjoyed both museums and would return. The Museum of Illusions, in particular, works well for adults because the tricks depend on how you frame the picture and how the eye reads the scene.

Still, the age balance matters. One practical assessment is that the Big Fun Museum is mainly for children, while adults may get more from the Museum of Illusions. If your group wants serious art, detailed history, or quiet reflection, this is not the right use of your $35.

Timing, access, and practical details

The ticket is valid for one day, with availability and starting times shown when you check dates. You should plan enough time for both museums instead of treating them as a quick photo stop. The experience has no guide, so the pace is yours.

Pictures are allowed, and photography is central to the attraction. Bring a phone with enough battery and leave room for several attempts. The best results often come from adjusting your position rather than accepting the first shot.

The museums are accessible for people with reduced mobility. That is helpful for families and mixed groups, though individual room layouts and temporary closures can change. Some areas have closed for maintenance, so do not assume every single display will be operating on the day.

Holiday hours require extra care. From December 19, 2025 through January 10, 2026, the museums are open from 11:00 a.m. to 9:00 p.m., except for special hours on December 24, December 25, December 31, and January 1. On December 24 and December 31, hours are 11:00 a.m. to 7:00 p.m. On December 25 and January 1, opening begins at 1:00 p.m. and ends at 9:00 p.m.

Free cancellation is available up to 24 hours before the visit for a full refund. You can also reserve now and pay later, which helps if your Barcelona schedule is still changing.

The main strengths and weak spots

The strongest part of the experience is the amount of easy, social fun packed into one admission. The Big Fun Museum keeps changing its theme, and the Museum of Illusions gives you a second set of photo challenges nearby.

The close locations are another clear advantage. You do not lose time arranging a taxi or public transport between attractions, and you can fit the visit around other Rambla plans.

The weak spots are mostly about polish and expectations. Some items have needed repair, and occasional maintenance closures can reduce the number of working displays. The Museum of Illusions can also feel less substantial if you expect a large collection rather than painted scenes on walls.

Staff service may vary between the two buildings. The Big Fun Museum has been described as helpful, while the Museum of Illusions has felt less friendly to some visitors, though not rude. Since this is a self-guided attraction, staff interaction is limited in any case.

Should you book the Big Fun Museum and Museum of Illusions?

Book it if you want a playful break from Barcelona’s formal sights, especially if you are traveling with children, teenagers, a partner, or friends who enjoy taking pictures. The combination is strongest when you have time to try the poses, use the marked viewpoints, and laugh at the results.

Skip it if your priority is original art, serious history, or a polished museum collection. At $35, the ticket earns its value through shared entertainment and photographs, not through scholarly exhibits.

For most suitable groups, I would visit both buildings rather than choosing only one. The Big Fun Museum offers the broader range, while the Museum of Illusions supplies the sharper perspective tricks. Together, they make a cheerful, low-pressure addition to a Barcelona day.
