Ekenäs Archipelago Overview

Ekenäs Archipelago National Park, or Tammisaaren saariston kansallispuisto in Finnish, is a stunning maritime national park located in southern Finland, in the Gulf of Finland. Encompassing approximately 19 square miles (50 square kilometers), this national park protects a diverse coastal environment filled with rocky islets, lush forests, and rich marine life.

It is situated near the town of Ekenäs (Tammisaari), part of Raseborg, and is one of Finland’s finest archipelago parks, offering breathtaking scenery and an abundance of wildlife. The park, established in 1989, forms part of a larger conservation network aimed at protecting the fragile Baltic Sea ecosystem.

The terrain of Ekenäs Archipelago National Park is defined by its collection of small islands, skerries, and islets that vary from smooth rocky shores to dense forests. The landscape is shaped by the retreat of the Ice Age glaciers, leaving behind rugged cliffs, narrow channels, and glacially polished rock formations.

Some of the park’s larger islands, such as Jussarö and Älgö, are covered with mixed forests dominated by pine, birch, and spruce, while smaller islands often feature low-growing vegetation, including sea buckthorn and juniper. Jussarö, in particular, is a fascinating destination, blending natural beauty with remnants of old iron mines and abandoned military sites. The clear coastal waters host extensive meadows of bladderwrack and other seaweeds, vital for marine biodiversity.

Ekenäs Archipelago is home to a rich variety of wildlife, with the park serving as an important nesting ground for numerous bird species. Among the most notable birds found here are the white-tailed eagle, common eider, Arctic tern, and black guillemot. Many migratory birds use the park as a resting point, making it an excellent destination for birdwatchers.

The waters surrounding the park are inhabited by the Baltic ringed seal and grey seal, which can sometimes be spotted lounging on the rocky outcrops. The islands also support small populations of deer and foxes, while the forested areas provide habitats for red squirrels and various small mammals. Additionally, the underwater world of the park is teeming with fish such as perch, pike, and Baltic herring, making it an attractive location for fishing enthusiasts.

One of the most popular aspects of Ekenäs Archipelago National Park is its untouched and peaceful nature, ideal for outdoor activities. Visitors can explore the park by boat or kayak, weaving through the maze of islands and enjoying the pristine surroundings. The park’s hiking trails, particularly on Jussarö Island, provide excellent opportunities for exploring historical sites alongside nature.

Camping is allowed in designated areas, and there are a few rustic huts available for overnight stays. Fishing, snorkeling, and diving are also popular activities, as the clear waters offer excellent visibility for marine exploration. The park’s location along the Baltic Sea’s coastal route makes it a favorite stop for sailors and boaters.

Ekenäs Archipelago National Park faces conservation challenges primarily due to the fragile marine ecosystem of the Baltic Sea. Issues such as eutrophication, caused by agricultural runoff and pollution, pose threats to water quality and marine biodiversity.

Additionally, climate change and increasing tourism require careful management to maintain the park’s delicate balance. Despite these challenges, Finland’s conservation efforts, including marine protection programs and habitat restoration initiatives, have helped preserve this unique environment. Strict guidelines are in place to ensure responsible tourism, allowing visitors to experience the park’s beauty while minimizing environmental impact.

Ekenäs Archipelago National Park Highlights

Popular

Ekenäs Archipelago National Park, located in the Baltic Sea off the southern coast of Finland, is known for its rugged island landscapes, rich marine biodiversity, and thriving populations of wildlife. The park consists of numerous islands, skerries, and rocky shores, providing a habitat for a variety of mammals and marine species.

Grey Seal (Halichoerus grypus)
One of the most iconic species of the Baltic Sea, the grey seal is commonly seen resting on the rocky islets of the archipelago. These large marine mammals are excellent swimmers and skilled hunters, feeding primarily on fish.

Harbor Seal (Phoca vitulina)
Smaller than the grey seal, the harbor seal is another marine mammal that inhabits the waters around the park. They are often spotted lounging on rocks or swimming near the shoreline, using their agility to hunt for fish and crustaceans.

European Otter (Lutra lutra)
The elusive European otter thrives in the waterways and coastal environments of the park. With its sleek body and webbed feet, it is well adapted to a semi-aquatic life, hunting for fish and small invertebrates in the shallow waters.

White-Tailed Deer (Odocoileus virginianus)
Although native to North America, the white-tailed deer has been introduced to parts of Finland and can sometimes be found in the wooded areas of the archipelago, where it forages for leaves, berries, and grasses.

Raccoon Dog (Nyctereutes procyonoides)
Originally from East Asia, the raccoon dog has established a presence in Finland, including the Ekenäs Archipelago. This nocturnal omnivore is known for its thick fur and scavenging habits.

Red Fox (Vulpes vulpes)
A common sight in the park, the red fox is an adaptable predator that thrives in various habitats. It preys on small mammals, birds, and insects, often hunting along the rocky shores and forested parts of the islands.

Eurasian Lynx (Lynx lynx)
Though rare, the elusive Eurasian lynx is a top predator in Finland’s forests. This solitary feline primarily hunts small deer and hares, blending seamlessly into the wooded terrain of the archipelago.

European Hedgehog (Erinaceus europaeus)
A familiar nocturnal creature, the European hedgehog can sometimes be found foraging in the undergrowth of the archipelago’s forests. It feeds on insects, worms, and small amphibians.

Ringed Seal (Pusa hispida)
This small and resilient seal species is well adapted to cold environments and occasionally appears in the brackish waters of the Baltic Sea. It relies on ice formations for breeding and pupping, though it also utilizes rocky shores.

Moose (Alces alces)
The largest land mammal in the region, moose sometimes venture into the park’s wooded areas, especially in search of food. They are strong swimmers and can cross between islands when necessary.

Birds

Ekenäs Archipelago National Park is a haven for birdlife, with its diverse marine and forested habitats attracting a wide range of seabirds, raptors, and migratory species.

White-Tailed Eagle (Haliaeetus albicilla)
One of Europe’s largest birds of prey, the white-tailed eagle is often seen soaring above the islands or perching on rocky cliffs. It primarily hunts fish but also scavenges along the shores.

Common Eider (Somateria mollissima)
This sea duck breeds on the islands and is well known for its soft down, which is used for insulation. Males have striking black-and-white plumage, while females are brown and well-camouflaged.

Black Guillemot (Cepphus grylle)
A characteristic bird of the Baltic Sea, the black guillemot nests in rocky crevices along the shorelines. Its black body, white wing patches, and red feet make it easy to identify.

Eurasian Oystercatcher (Haematopus ostralegus)
With its distinctive black-and-white body and bright red bill, the Eurasian oystercatcher is commonly seen foraging along the coastal areas, searching for mussels and shellfish.

Great Cormorant (Phalacrocorax carbo)
A large, dark waterbird, the great cormorant is often spotted drying its wings on rocks after diving for fish. It forms colonies on some of the park’s islands.

Arctic Tern (Sterna paradisaea)
Known for its extraordinary migration from the Arctic to the Antarctic and back, the Arctic tern nests on the islands of Ekenäs, where it fiercely defends its territory.

Razorbill (Alca torda)
This black-and-white seabird resembles a small penguin in appearance and behavior. It nests in rocky crevices and dives deep into the sea to catch fish.

Barnacle Goose (Branta leucopsis)
A common sight in spring and autumn, the barnacle goose stops in the archipelago during migration. Some also nest in the area, grazing on grassy patches near the shore.

Mute Swan (Cygnus olor)
A graceful and imposing bird, the mute swan is often seen gliding across sheltered bays. It is known for its white plumage, curved neck, and orange bill.

Northern Goshawk (Accipiter gentilis)
