Most port cities are defined by what they export. Kotka seems defined by what it plants.
By all logic, a city of 50,000 people driven by logistics, cargo ships, and the paper industry should be grey, loud, and strictly functional. Yet, Kotka has spent the last few decades systematically turning its industrial scars into some of Northern Europe’s most impressive parks.
It is a place where an oil terminal has become a silent meadow, a polluted bay is now an award-winning water garden, and a Russian Emperor’s fishing lodge sits just minutes away from modern docks.
Kotka makes for an easy summer day trip from Helsinki, but it is not a resort built for tourists. It is a working city that decided to build a better version of itself. Here are the best things to do in Kotka.
The Ecological Miracle
Sapokka Water Garden
If you want to understand Kotka’s transformation, start here. Fifty years ago, Sapokka was a eutrophied, muddy bay—a forgotten backyard of the city. Today, it is one of Finland’s most awarded parks.
The transformation is aggressive. A massive waterfall was constructed to tumble down a rocky hill, not just for aesthetics, but to pump oxygen into the water and create a sonic barrier against the city noise.
In early June, the contrast is stark. The rhododendrons and azaleas bloom with a ferocity that feels almost tropical, set against the cool, pale light of the Nordic summer. Look closely at the rocks: bronze sculptures of animals by Hannele Kylänpää are hidden in the crevices, treating the park not as an exhibition space, but as a habitat.
From muddy bay to award-winning garden: the view across Sapokka.
The massive waterfall isn’t just for show—it oxygenates the water and blocks city noise.

The Anti-Tropical Aquarium
Maretarium
Most aquariums try to dazzle you with sharks and neon corals. Maretarium does the exact opposite. It is proudly, stubbornly local.
There are no exotic show-offs here. Instead, you meet the real residents of the Finnish Baltic Sea and lakes. You get a pencil and a checklist, turning the visit into a study of the gloomy, fascinating world beneath the dark surface of local waters.
The stars are the pike (hanging motionless like underwater logs), the perch, and the oddly charming eelpout. The massive main tank replicates the Baltic Sea environment; watching a school of silver herring swirling in the deep, cold water is surprisingly hypnotic. It is an honest look at nature as it actually is in this latitude.

From Oil to Silence
Catherine’s Park (Katariinan Meripuisto)
For decades, this peninsula was an oil terminal, covered in tanks and fenced off from the public. Today, the tanks are gone, replaced by meadows, walking paths, and silence.
Situated on the tip of the island, it faces the open sea and takes the full force of the wind. The “Lighthouse Village” offers a surreal photo opportunity: replica models of some of Finland’s best-known lighthouses standing on dry land.
But the most poignant spot is Anchor Island. You will see a large anchor and perhaps some candles. This is a designated site for scattering ashes into the sea—a final resting place for those who lived their lives by the water. It is simple, respectful, and completely open to the elements.

The Wave of Glass
Maritime Centre Vellamo
In a landscape of cranes and containers, Vellamo disrupts the horizon. It looks like a giant abstract wave made of glass and steel crashing onto the pier.
The facade is covered in thousands of glass panels that reflect the sky, creating an effect like shimmering ice. Inside, the building houses the Maritime Museum of Finland. The scale is immense—vessels float in the air in a hall that feels more like a cathedral than a museum.
Don’t miss the small, modest boat named Victoria. It belonged to Tove Jansson, the creator of the Moomins. She used this boat to travel to her solitary island cottage in the Gulf of Finland, a reminder that for Finns, the sea is often a path to solitude.
The glass facade of Vellamo mimics a giant wave crashing into the industrial port.

The Old Soul
Isopuisto Park
While Sapokka is a modern experiment, Isopuisto is history. It surrounds the Orthodox Church of St. Nicholas (1801), the oldest building in Kotka and a remnant of the Russian era.
The design is classic English landscape garden: wide lawns, old trees, and gravel paths. But in early summer, the atmosphere shifts. The park’s massive collection of azaleas blooms in shades of violent pink and purple, creating a strange, beautiful visual clash with the restrained Neoclassical columns of the church.

The Impressionist River
Jokipuisto Riverside Park
This is not a natural riverbank. Located about 9 km from the city centre in the Karhula district, this park is a deliberate homage to Claude Monet. The gardeners didn’t just plant flowers; they engineered a view.
The park is built on a slope leading down to the Kymi River, with water channelled through stone distinct paths and ponds. It is architectural, precise, and looks like it fell out of an Impressionist painting. It requires a short trip out of town, but it is worth the detour to see how a public space can be designed with the precision of an art gallery.

Nature’s Spice Rack
Redutti-Kotka Herb Garden
Back in the centre, tucked behind the redbrick walls of a former military redoubt near Haukkavuori Tower, this garden feels like a secret. It is a sensory experience, packed with over a hundred varieties of herbs.
There is no grand monument here, just the smell of rosemary, mint, lemon balm, and hyssop trapped within the old fortress walls. It is a quiet place to sit and realise that a structure built for war is now used to grow tea ingredients.

The Emperor’s Hideout
The Imperial Fishing Lodge
Five kilometres north of the centre, the Kymi River roars through a gorge with raw natural power. Sitting calmly next to the rapids is a modest wooden house.
Built in 1889, this was the summer escape of Emperor Alexander III. At the time, Finland was an autonomous Grand Duchy within the Russian Empire, and the conservative Tsar came here not to rule, but to hide. He chopped firewood and fished for salmon, while Empress Maria Feodorovna peeled potatoes in the kitchen.
The museum preserves the interior, but the context is outside. Standing on the rocks by the deafening rapids, you understand the appeal: it is a place so loud with nature that it drowns out politics.

The Forest Utopia
Sunila District
A short drive east of the city, Sunila is a pilgrimage site for architecture enthusiasts. Designed in the 1930s by Alvar Aalto, Finland’s most famous architect, it was a radical social experiment.
Aalto designed a factory and a residential area as a single organism. He believed factory workers deserved light, air, and aesthetics. He called it “The Forest Town.”
Today, the white functionalist buildings standing amongst the tall pines look like a vision of the future from the past. It is clean, geometric, and uncompromisingly modern—a stark contrast to the wooden villas usually associated with Finnish summers.

Travel Notes
Kotka, Finland: Practical Guide
The Verdict: Kotka isn’t a postcard; it’s a project. The transformation of industrial scars into green sanctuaries commands respect. This place offers a necessary visual shock: heavy industry coexisting with delicate landscape architecture. Unpretentious and honest, it remains a working city—one that just happens to love its flowers.
If you arrive when the petals have fallen and the sea has frozen, the city transforms into a different world. It’s no longer about colour, but about snow and silence. Read my guide on what to really expect from a Finnish winter.
