If you like playful oddities, this pair delivers. Big Fun Museum and the Museum of Illusions turn Barcelona’s Rambla into a 3D-photo playground with enough goofiness for adults and kids.

I especially like that you get variety fast: one museum leans into interactive, silly rooms, and the other runs a long string of 3D illusion scenes made for doing the pictures. One thing to keep in mind is the pace, the attractions are listed as short blocks, so if you want slow, careful photo time, you’ll likely need a bit more time than the headline duration suggests.

Key Highlights Before You Go

• Two museums, one ticket feel, so you do more than just a quick walk-through.
• Rambla location, with easy public-transport access and lots to do nearby.
• Big Fun’s themed rooms, including the upside-down experience and a ball pool rest area.
• Museum of Illusions has 600+ meters of 3D-style paintings that are built for photos.
• Photo prompts for the dramatic moments, including spots where you can take a fall safely for the picture.

Big Fun Museum and the Rambla Advantage

Big Fun Museum sits right where the action is, on Barcelona’s Rambla. That matters more than it sounds. When your attractions are central, you spend less time commuting and more time actually doing the fun part.

This place is built for more than standing and reading. It’s designed as a set of themed rooms that guide you toward interaction and silly moments, which is perfect if you’re traveling with kids, a group with mixed ages, or anyone who gets bored by quiet museums.

The ticket includes admission, and the museum mix is clear from the start. You’re not choosing between different experiences later, you’re doing both in one outing: the family-friendly chaos of Big Fun first, then the 3D illusion photo run.

One practical note: the experience is listed at about 1 to 2 hours overall, but Big Fun is specifically listed as a 2-hour stop. In plain terms, you should treat this as flexible. If you’re the kind of person who wants to try every photo spot, plan extra time so you don’t feel rushed.

Big Fun Museum: Five Themed Rooms Built for Play

Big Fun Museum feels like a shortcut to fun. You get multiple themes without the fatigue of a long museum circuit. Instead of one big exhibit, you move through separate rooms, each with its own vibe, props, and photo angles.

Here are the main themed spaces, as listed:

• The House of the i ante
• Candy Museum
• The House upside down
• Guinness Museum
• Ball pool (rest area)

That spread is what I like most. The upside-down concept gives you instant photo ideas. The Candy Museum adds a playful, colorful mood. The ball pool is a real breather for families, and it helps younger kids burn off energy without forcing everyone to sprint through the rooms.

The upside-down house: the photo engine

The House upside down is the kind of attraction that makes you immediately understand what to do. Gravity is turned into a joke. You’ll likely spend more time posing than walking, because it’s hard to resist trying the scene from different angles.

If you’re traveling with kids, this is usually the room that keeps the energy up. If you’re traveling with adults who don’t usually “pose for photos,” the upside-down element is still a simple win, it gives you a clear target without needing instructions or a guide.

Candy Museum: fun, not complicated

The Candy Museum is a lighter counterpoint to any darker corners in the building. It’s the kind of stop where you can slow down just enough to enjoy the look, then get moving again when your group is ready.

It’s also a good option if someone in your group needs a calmer moment after more intense scenes. You keep the outing moving, but you don’t force the whole group into one mood for the entire visit.

Guinness Museum: a built-in theme

The Guinness Museum gives the visit a recognizable branding idea. Even if you don’t know the backstory, the name signals that you’re in for fun, quirky display energy rather than a heavy educational slog.

What this means for you: you can enjoy it even if your group’s interests vary. It adds a familiar word to the mix, and it tends to spark casual conversation without requiring background knowledge.

Ball pool rest area: practical downtime

The ball pool (rest area) is genuinely useful. It’s not just a distraction, it’s a built-in recovery zone. Kids can release some energy, adults can sit or stand and regroup, and everyone gets a reset before the next round of photos.

When you’re trying to do two museums in one outing, these rest pockets matter. They prevent the day from turning into a nonstop treadmill.

A possible drawback: the mood can run intense

One of the rooms in Big Fun includes a horror-themed segment, and it can be a little scary for smaller kids. That does not mean it’s inappropriate, but it does mean you should read the room and adjust. If you’re bringing children, consider doing this part when they’re already warmed up, not at the end of a long day.

For the best results, set the expectation that the scary part is part of the fun, then let your kid opt in or out. The overall layout is family-focused, but not every moment is soft.

Museum of Illusions: 600+ Meters of Photo-Ready Scenes

After Big Fun, the Museum of Illusions flips the style. Instead of playful rooms, you get an extended path of scenes designed around 3D effects and photo setups.

The big selling point is scale and feel. This museum is described as more than 600 meters of paintings with 3D effects. That’s long enough that you’ll keep turning corners and discovering new scenes, not just seeing a few quick set pieces.

The concept is also very visual and specific. You can end up in scenes like being in a bathroom next to political celebrities of the moment, or being with FC Barcelona players celebrating a victory. It’s odd, pop-culture friendly, and designed to make you laugh at how impossible the scene looks.

How the photo moments work

This museum also includes clear photo guidance. The experience notes that the exact point where you can take the fall will be indicated, so you can capture dramatic scenes the way the attraction intends.

Why that matters: you don’t need to figure out staging, timing, or angles on your own. The museum nudges you toward the spot where the illusion reads best, which saves time and reduces frustration.

What to expect as you walk through

As you move through the route, the illusion scenes are the center of gravity. You’ll likely find yourself pausing often. People take pictures, reset their stance, and try again. If you like repeat attempts and better angles, this is the kind of place where you can have fun without needing extra tickets or add-ons.

Also, because the scenes are paintings with 3D effects, they tend to work consistently in indoor lighting. That’s helpful in a city where sun and shadow can ruin photo plans.

A practical consideration: plan your group’s rhythm

Even though this stop is listed as 1 hour, in real life the length depends on photo enthusiasm. If you treat it like a casual stroll, you might finish quickly. If you keep testing the best spot for the best shot, it can take longer.

No matter what, this museum is still worth it because it changes your “walking route” into a “photo scavenger hunt.” That keeps attention high.

Timing Your Visit Without Feeling Rushed

The listing frames the full outing as about 1 to 2 hours, but it also assigns 2 hours to Big Fun and 1 hour to Illusions. With that mismatch, the smartest approach is to plan like a flexible schedule.

Here’s how I’d time it for an easy Barcelona day:

• Start with Big Fun if your group needs warm-up energy. The upside-down rooms and ball pool help kids and adults settle in.
• Then move to Illusions when you’re ready for the photo run. The guidance points, including the fall spot, make it easier to move along with purpose.

The museum hours are daily, from 11:00 AM to 9:00 PM. That gives you a lot of flexibility. If you’re also doing other Rambla stops, a late-morning entry helps you avoid the crush that can happen later in the day.

Also check comfort. This is mostly indoor time, so you’ll be sheltered from weather. That’s a real advantage in Barcelona when the day flips from sunny to breezy.

Price and Value: Two Admissions for One Outing

At $36.12 per person, you’re paying for entry to both experiences in one bundled outing. The value comes from the variety you get in a single ticketed block: one museum is hands-on silly and family-friendly, the other is a longer 3D photo route.

This is the kind of purchase that makes sense when you want an indoor plan that still feels like an adventure. You’re not buying a single-room exhibit. You’re getting multiple spaces, multiple themes, and a clear shift in style.

Snacks like cotton candy are not included, so if you know your group will want a treat, keep that in mind. It’s not a reason to skip, it’s just a budget cue. The good news is the museum setup includes a rest area, and you’re close to plenty of other options outside.

Given the rating of 3.9 from 32 reviews, the experience seems to land well for families and for people who enjoy playful surprises. The biggest “fit” factor is your willingness to participate, not just look.

Who This Is Best For (And Who Might Skip It)

This combo makes the most sense if you want fun first. It’s built for people who like interacting, posing, and laughing at the weirdness.

I think it’s a great pick for:

• Families with kids who need active, low-stress attractions
• Couples who enjoy photo moments and playful challenges
• Groups with mixed ages, because you get different moods in one outing

If your ideal Barcelona day is quiet galleries and long explanations, you might not love the format. These museums prioritize immediate fun and repeat photo moments over quiet contemplation.

And if you’re bringing young kids, the horror-ish corner in Big Fun is worth noting. It can add a jolt of adrenaline, which some kids love, but it can be scary for others.

Should You Book Duo Museum of Illusions + Big Fun Museum?

Book it if you want an efficient, central indoor plan with two distinct styles. The Rambla location keeps logistics simple, and the mix of themed rooms plus a long 3D illusion route gives you enough variety to keep most people interested.

Don’t book it if you hate interactive attractions or you only want serious museums with deep labels. Also, if your group is sensitive to even mild scary themes, consider whether the horror-themed area in Big Fun will work for your kids.

One final tip: treat this as a photo outing. If you come with that mindset, the museums deliver what they promise: funny, weird scenes where you can actually create the picture, not just watch it.
