From ice cream kiosks to and parks on every corner, Helsinki is wonderfully kid-compatible. There’s space to run, places to climb, and no one bats an eye if your child decides to narrate the entire zoo visit out loud. Bring a stroller, pack layers (this is still Finland), and let curiosity lead the way.
Here’s how to fall in love with the Finnish capital, one family-friendly stop at a time.
1. Linnanmäki – Screams and Cotton Candy (the Good Kind)
There’s no point pretending: if you’re in Helsinki with kids, you’re going to end up at Linnanmäki. And honestly? You should. This charming old-school amusement park has been making Finnish families squeal with joy since 1950. There are rollercoasters for the brave, carousels for the cautious, and a free viewing tower for grandparents who “just want to watch.”
And then there’s the wooden rollercoaster—Vuoristorata—a true national treasure. Built in 1951 and still clattering along with a standing brakeman riding the back (yes, really), it’s a creaky, thrilling blast from the past. Finns grow up with it. Parents ride it with misty eyes. Kids come off it wide-eyed. It’s the kind of ride that somehow feels like both a thrill and a family tradition.
Bonus: admission to the park is free, and so are many of the rides for younger children. You’ll also find popcorn, waffles, and probably a seagull or two trying to steal your ice cream. Classic.
2. SEA LIFE – Sharks, Seahorses, and One Smiling Superhero
Right next to Linnanmäki Amusement Park, you’ll find SEA LIFE, Finland’s largest marine aquarium—and a perfect rainy day adventure. Here you can come face to face with all kinds of underwater wonders, from elegant seahorses and sharp-toothed piranhas to the dramatic, twitchy presence of an electric eel.
The highlight? Walking through a glass tunnel beneath the ocean tank, with sharks circling silently above your head. It’s both peaceful and thrilling—and a big hit with kids who want that little jolt of excitement without the rollercoaster.
And don’t miss the aquarium’s weirdest (and possibly cutest) resident: the axolotl, a rare amphibian from Mexico that looks like a smiling cartoon character wearing a fluffy gill scarf. Beyond the charm, it comes with a real-life superpower: if an axolotl loses a limb or even a gill, it can grow it back. Eat your heart out, superheroes.
3. Korkeasaari Zoo – Meet the Enigmatic Snow Leopard
Hop on a short ferry from the Market Square—or stroll across the bridge from Mustikkamaa—and suddenly you’re on an island filled with camels, monkeys, and one very famous big cat. Korkeasaari Zoo, founded back in 1889, is one of the oldest zoos in the world. Its first residents included a polar bear from the Arctic Sea and parrots that had hitched a ride on ships. Today, it’s home to around 150 species, from lynxes to reindeer—but the undisputed star is the snow leopard.
Korkeasaari has played a leading role in the international conservation of snow leopards, coordinating breeding programs since the 1960s. More than a hundred cubs have been born here—more than in any other zoo in the world. It’s not just about seeing animals; it’s about giving endangered species a fighting chance.
The zoo’s forest paths wind past rocky cliffs, open sea views, and well-designed enclosures, with playgrounds and picnic spots tucked in along the way. Special events like the popular Night of the Cats in September add a little extra magic.
Korkeasaari is open every single day of the year, rain, shine, or snow. And while the classic ferry ride from the city centre will run until 2026, after that, a brand-new pedestrian bridge will offer even easier access straight from the mainland.
4. Natural History Museum – Elephants, Dinosaurs and a Two-Headed Calf
Step inside the Natural History Museum (Luomus), and you’re greeted by a full-sized elephant—the unofficial doorman of one of Helsinki’s most charming and curiosity-filled museums.
This place has been fascinating local children since 1923, and it’s easy to see why. The halls are filled with stuffed animals from every corner of the globe: towering moose, polar bears, exotic birds, and a slightly unnerving bear that always seems to be watching. There are dinosaur skeletons, fossils, and enough rocks to spark a lifelong geology obsession.
And of course, there’s the two-headed calf—a wonderfully weird crowd favorite that’s been delighting and puzzling kids (and adults) for decades.
Educational, a little eccentric, and full of photo ops, Luomus is a perfect stop for curious families—and a great backup plan for rainy days.
5. Suomenlinna – A Fortress, a Picnic, and Dark Tunnels to Run Through
It’s not every day you get to ride a ferry to a UNESCO World Heritage Site that also happens to have cannons, tunnels, and picnic spots. Suomenlinna Sea Fortress is a dream for kids with big imaginations and parents who want a dose of history with their juice boxes.
Let the kids lead the way through stone archways and secret paths while you enjoy the sea breeze. There’s also a small toy museum, cafés, and enough grassy hills for a thousand somersaults. Bring a blanket and turn it into a fortress of your own.
6. Oodi Library – See the Future of Libraries
Yes, a library. But not just any library. Oodi is Helsinki’s futuristic living room—complete with kids’ play areas, story hours, art rooms, and even a 3D printer in case someone suddenly needs a miniature plastic hippo.
The children’s section upstairs has a play area, books in multiple languages, and a soft, calm vibe that feels like a nap waiting to happen (the good kind). Parents can sip coffee with a view of Parliament. Everyone wins.
7. Tropicario – Snakes, Crocodiles, and a Lizard That Doesn’t Need a Date
Tucked away inside an unassuming apartment block in Vallila, Tropicario is Helsinki’s very own reptile house—and a hidden gem for animal lovers with a taste for the scaly and slithery.
Its claim to fame? More giant constrictor snakes than anywhere else in the Nordics. If you’ve ever wanted to be eye-to-eye with a python the size of a firehose, this is your chance. There’s also a crocodile, and the true oddballs of the collection: the black water monitors—the only ones in Europe, and even more impressively, they’ve managed to reproduce parthenogenetically (yes, that means without needing a mate).
Equal parts creepy and fascinating, Tropicario is a perfect indoor stop when you want to impress curious kids—or slightly freak out their parents.
8. Heureka – Science Center for All Ages
Located in Vantaa, just a short train ride from Helsinki, Heureka is Finland’s premier science center—a place where curiosity comes alive through hands-on exhibits, interactive displays, and mind-bending experiments. It’s a hit with families, offering everything from a rat basketball arena to a giant Foucault pendulum that swings with hypnotic grace.
But Heureka isn’t just for kids. Adults will find plenty to engage their inner scientist, especially during the center’s special evenings designed exclusively for those aged 18 and over. One standout is the annual H18: Halloween, a spooky science soirée that transforms the entire center into a carnival of curiosities. Picture this: the lights dim, eerie sounds echo through the halls, and guests explore the exhibits with a drink in hand. Highlights have included immersive horror shows like the “Subway-blind” experience, where participants navigate a pitch-black maze, relying solely on their senses.
So whether you’re a family seeking interactive fun or an adult looking for a unique night out, Heureka offers a universe of discovery that’s both educational and entertaining.
