Brussels blew my mind in ways I never expected. My first night there, sitting in Grand Place as the gothic towers lit up gold against the night sky, a street musician started playing jazz while I devoured the best waffle of my life. That moment pretty much sums up Brussels: unexpectedly magical, deeply cultural, and always delicious.
After discovering the best things to do in Brussels, I can tell you this city is seriously underrated. From watching the sunset from the top of Mont des Arts (with locals sharing wine and cheese on the steps) to hunting down the weirdest comic murals in the city center, Brussels has this perfect mix of grandeur and quirky charm. Let me show you why this city deserves way more than a quick stopover.
Best Things to Do in Brussels for Young Adults
Looking for the coolest things to do in Brussels for young adults? Explore the Heart of Brussels at the Grand Place, indulge in Belgian Chocolate Mastery, enjoy panoramic views from Atomium’s Top Sphere, and hunt for treasures at the Marolles Flea Market. Whether you’re into history, food, or unique experiences, here are the top attractions to visit in Brussels.
1. Explore the Heart of Brussels at the Grand Place
Few city squares are as striking as Grand Place, where gold-trimmed guildhalls and gothic spires surround a cobblestone plaza. This UNESCO-listed square is the cultural core of Brussels and a fantastic starting point for any visit. The ornate Town Hall, King’s House (Maison du Roi), and vibrant flower markets make every corner photogenic. Stick around after dark—the buildings light up beautifully and the vibe shifts to something almost cinematic.
I grabbed a waffle from Maison Dandoy nearby and found a spot on the steps to soak in the view. Whether you’re admiring the architecture, catching live performances, or people-watching with locals, the energy here is electric. August visitors should catch the Flower Carpet event—it only happens every two years. It’s the kind of place you’ll return to more than once, no matter how short your trip is.
2. Savor the Flavor of Belgian Chocolate Mastery
If you love sweets, getting hands-on with a Belgian Chocolate Workshop is a no-brainer. Brussels takes its chocolate seriously, and these experiences let you taste and create your own confections. One of the best options is The Belgian Chocolate Workshop, which offers a 2.5-hour session where you’ll make over 35 pralines and mendiants, all while sipping rich hot chocolate.
I signed up with a couple of friends, and we left with chocolate-stained aprons and boxes of our creations. The atmosphere is casual and fun, with no cooking skills required. It’s a great way to spend an afternoon, especially if you’re traveling with a group. Plus, you’ll walk away with treats you actually made—way better than just buying a box from a store. It’s a sweet memory in more ways than one.
3. Catch the Sunset from Atomium’s Top Sphere
For panoramic views with a twist, head to the Atomium, one of Brussels’ most iconic landmarks. Shaped like an iron crystal, this futuristic structure offers a 360° observation deck in its top sphere. As the sun begins to set, you’ll see the city stretch out beneath you—golden light spilling over rooftops, parks, and modern towers.
I went up about an hour before sunset and loved watching the light shift through the glass panels. The interior is just as memorable, with rotating exhibits on design, architecture, and science.
Escalators and tunnels connect the spheres, and their retro lighting gives off serious sci-fi vibes. Go in the late afternoon for smaller crowds and great lighting for photos. Admission includes access to all levels, so take your time exploring. If you’re combining sights, Mini-Europe is right next door.
4. Uncover Hidden Gems in the Marolles Flea Market
Kick off your day with a treasure hunt at the Marolles Flea Market, held every morning at Place du Jeu de Balle. This sprawling open-air market has everything from antique furniture and vintage clothing to retro toys and random oddities. It’s a local favorite and a fantastic way to experience the city’s more eclectic side. If you enjoy rummaging for unique finds, this spot is hard to beat.
I once scored an old brass candlestick for a few euros—it now sits proudly on my bookshelf. Haggling is expected, so don’t be shy to bargain a little. After browsing, take a short walk to Mazette, a lively brewery and café that serves up house-made beers, sourdough bread, and hearty seasonal dishes. Whether or not you find the perfect vintage piece, the market’s quirky charm and neighborhood vibe make it well worth a visit.
5. Dance the Night Away at Fuse
When night falls in Brussels, Fuse is where the real party begins. This iconic techno club in Marolles has been a mainstay of the city’s electronic scene since the ‘90s. Its industrial vibe, massive sound system, and multi-room layout create a raw, high-energy atmosphere that keeps the dance floor packed well into the morning.
I went on a Friday when a Berlin-based DJ was headlining, and the crowd’s energy was contagious. Whether you’re deep into techno or just want to experience a proper European club night, Fuse doesn’t disappoint. Check the lineup before going—sets can range from minimal to hard techno. Doors open late and queues build quickly, so arriving early helps. Grab a drink upstairs to start slow, then lose yourself in the rhythm below. For young adults chasing a wild night out in Brussels, Fuse hits the mark.
6. Bike Through Brussels’ Green Escapes
Rent a bike and explore Brussels’ quieter side by pedaling through its leafy urban parks. Parc du Cinquantenaire and Bois de la Cambre are two of the city’s best green spaces for a scenic, laid-back ride. From elegant archways to wooded trails, they offer the perfect mix of city and nature.
I followed a bike path that wound through the Etterbeek area into the woods of Bois de la Cambre, where locals picnicked and played frisbee. It felt like a secret retreat from the busier neighborhoods.
Several rental shops like Pro Velo offer affordable hourly and daily rates. The paths are easy to navigate, and most major parks connect through the city’s expanding network of cycling lanes. Whether you’re solo or with friends, this ride gives you a relaxed way to explore local life beyond the tourist zones.
7. Sip and Savor at a Belgian Beer Tasting
Belgium’s beer reputation isn’t just hype—it’s something you need to taste to believe. For a casual yet educational dive into the scene, book a tasting with Beer Experience Brussels, located right in the city center. Their 75-minute session offers a curated mix of lambics, Trappist ales, and seasonal brews.
I joined a small group inside a cozy private bar and sampled five distinct styles, each paired with a bit of history. The host knew his stuff but kept the tone fun and approachable. It’s a great intro whether you’re a craft beer nerd or just curious. They also offer a combined beer tasting and bar crawl if you’re up for more social energy. And yes, you’ll leave with a buzz and a few new favorites. Booking ahead is smart—sessions often sell out, especially on weekends.

8. Stroll Through the Enchanted Forest of Sonian
Just a 20-minute ride from downtown, the Sonian Forest feels like a completely different world. Spanning over 4,000 hectares, this UNESCO-listed beech forest offers peaceful trails, wildlife sightings, and plenty of space to breathe. It’s one of the best nature escapes for anyone looking to reset during a city trip.
We hiked part of the Red Trail Loop, which takes about 1.5 hours and winds past thick groves and quiet ponds. The paths are clearly marked, and you’ll often spot joggers, cyclists, and even horseback riders along the way.
Bring water, snacks, and a camera—the shifting light through the canopy is stunning. Entry is free, and the forest is open year-round, with fall being especially beautiful. Whether you walk a little or explore all day, Sonian is a refreshing contrast to Brussels’ urban buzz.
9. Laugh Out Loud at a Comedy Club
For a light-hearted night out, Kings of Comedy Club brings sharp jokes and big laughs in a cozy, underground setting. Located in Ixelles, this venue hosts a rotating lineup of Belgian and international comedians who tackle everything from local quirks to global absurdities. Shows are mostly in French, but English-language sets are common too—check the schedule in advance.
I dropped in on a Wednesday and ended up staying for both the open mic and the headliner. The vibe was casual, with drinks flowing and the audience fully engaged. If you’re traveling solo, comedy nights like this make it easy to strike up conversations with locals. Grab a table early if you want a front-row seat, or stick to the bar area for a more laid-back experience. It’s one of Brussels’ underrated gems when you’re looking to unwind and laugh without the club scene.
10. Get Lost in the Magic of Mini-Europe
Located right next to the Atomium, Mini-Europe is a compact theme park where you can stroll past 350 miniature landmarks from across the continent. From Big Ben and the Eiffel Tower to ancient ruins and erupting volcanoes, this quirky attraction squeezes a grand European tour into a single afternoon.
I didn’t expect to enjoy it as much as I did, but the detail in the models—and the humor behind some displays—really caught me off guard. There are even interactive exhibits, including buttons that launch tiny trains or simulate a Mount Vesuvius eruption.
It’s fun, a little odd, and surprisingly educational. Great if you’re traveling with friends and want something easygoing and different. Consider bundling your ticket with the Atomium for a full day of exploration and photo ops. Allow at least 1.5–2 hours for a relaxed visit.
11. Unravel the Mysteries of the Royal Greenhouses
Every spring, the Royal Greenhouses of Laeken open their doors for just three weeks, revealing one of Belgium’s most breathtaking hidden gems. Built in the 19th century for King Leopold II, the complex is a masterpiece of iron and glass filled with rare and exotic plants from around the world.
The experience feels like wandering through a tropical palace. I followed the walking route past towering palms, blooming azaleas, and long glass corridors filled with cascading flowers. The Winter Garden dome is the crown jewel, with its dramatic palm trees and royal elegance.
If you’re in Brussels between mid-April and early May, it’s absolutely worth timing your visit. Tickets are affordable, but book online early—they go fast. Wear comfy shoes and bring your camera—every angle here is photo-worthy. The atmosphere is serene and cinematic, especially around golden hour.
12. Glide Over the City on a Hot Air Balloon Ride
If you’re looking for a truly unforgettable view of Brussels, a hot air balloon ride with C-Air Balloonvaart offers just that. Flights typically take off from the Brabant region, just outside the city, providing sweeping aerial views of the skyline, countryside, and nearby castles.
We launched just after sunrise, and within minutes, rooftops turned to patchwork fields as we drifted silently above the city. The flight lasted about an hour, and the stillness in the air was surreal. Our pilot pointed out landmarks like the Atomium and Royal Palace of Laeken, and afterward, we toasted with champagne—a ballooning tradition.
The company also provides transportation from Brussels to the launch site, making the logistics easy. If you want to mark a special occasion or just see Brussels from a new perspective, this is one adventure that delivers.
