Ekenäs

Ekenäs Archipelago National Park occupies an island-studded coastal zone in the Uusimaa region of southern Finland, approximately 100 kilometres west of Helsinki. Established in 1989, the park protects roughly 52 square kilometres of islands, islets, and shallow sea along the outermost reaches of the Finnish archipelago. The town of Tammisaari (Ekenäs in Swedish) serves as the main gateway. The park is notable for its blend of Swedish-Finnish cultural heritage, with the surrounding area historically populated by Swedish-speaking coastal communities. Sheltered bays, granite skerries, and old-growth coastal forest create a landscape that draws naturalists, sailors, and kayakers throughout the summer season.

The park supports Finland's largest population of white-tailed eagle, with multiple breeding pairs nesting on forested islands. Eider duck, velvet scoter, and red-breasted merganser breed across the outer skerries, while black guillemots nest in rock crevices on wave-exposed islets. Ringed seals and grey seals are regularly observed hauling out on low-lying reefs in the outer archipelago. The shallow, sheltered bays are feeding grounds for great crested grebe, tufted duck, and common goldeneye. During spring and autumn migration, the park's coastal position makes it a bottleneck for raptors and passerines funnelling along the Finnish south coast.

The park encompasses diverse coastal habitats ranging from wave-washed outer skerries to sheltered meadows and alder carr on larger inner islands. Exposed rock surfaces carry extensive lichen mats, while sea buckthorn thickets colonize sandy and gravelly shores on outer islands. Old coastal meadows, historically grazed by cattle from mainland farms, harbour populations of seaside centaury, Baltic rush, and other species dependent on open, low-nutrient grassland. Restoration grazing has been reintroduced on several meadow islands. Scots pine and Norway spruce dominate forested areas, with some stands showing old-growth characteristics including standing dead wood and veteran trees.

Ekenäs Archipelago lies on the Baltic Shield, formed from Precambrian metamorphic and igneous rocks more than 1.8 billion years old. The dominant rock types include granites, gneisses, and rapakivi granites, all shaped by glacial erosion during the last ice age. The islands are classic examples of skerry topography created when the continental ice sheet gouged northwest-to-southeast trending valleys that later flooded as sea levels rose. Glacial polish and roches moutonnées are visible on many island surfaces. Post-glacial land uplift continues to raise the coastline, gradually merging shallow reefs into the island chain and exposing new land.

The park's southern coastal location gives it one of the mildest climates in Finland. Mean July temperature averages around 17°C, and the growing season is longer than elsewhere in the country. Sea ice forms in sheltered inner bays during cold winters but rarely closes the outer archipelago for extended periods. Winter storms bring strong southwesterly winds that can make boat travel dangerous. The maritime influence keeps temperatures above freezing even in winter some years. Late spring fog is common as the sea warms more slowly than the land.

The Ekenäs archipelago has been settled since prehistoric times; Stone Age seal-hunting camps are known from several islands. Swedish-speaking coastal communities dominated the area from the medieval period onward, establishing fishing villages and seasonal herding islands throughout the archipelago. The town of Ekenäs itself was founded in 1546. During the eighteenth century, the archipelago was a strategic military frontier between Swedish and Russian power, and several fortification sites remain. Traditional livelihood activities including fishing, seal hunting, and cattle herding on island meadows persisted into the twentieth century, shaping the cultural landscape that the park now partly manages.

Ekenäs Archipelago National Park was established in 1989 under Finnish legislation protecting national parks. The park was created to preserve both the natural archipelago ecosystem and the rich cultural heritage of the Swedish-Finnish coastal community. Management is carried out by Metsähallitus. Over the years the park's management plans have increasingly integrated restoration of traditional cultural landscapes, including the reintroduction of grazing cattle to overgrown island meadows. Cooperation with local communities and boat operators has been central to the park's visitor management strategy.

Boating and sea kayaking are the primary ways to explore the park. Marked water trails connect key landing sites across the archipelago. The island of Älgö features a nature trail through coastal forest and rocky shore habitats, with an observation tower offering views across the outer skerries. Bengtsår Island has a historic lighthouse open to visitors, and the restored fishing hamlet at Modermagen provides insight into traditional archipelago life. The park's outer islands offer prime conditions for seabird watching and grey seal observation. Winter skiing across frozen sea ice is possible in cold years.

The town of Tammisaari (Ekenäs) is the main access point, accessible by train from Helsinki in about 90 minutes. Seasonal boat connections operate from Tammisaari to the main park islands during summer. Metsähallitus maintains camping sites, lean-to shelters, and fire rings on designated islands. A visitor centre in Tammisaari provides maps, route planning assistance, and exhibits on the park's nature and culture. Kayak rentals are available from local outfitters. Most facilities are concentrated between June and August; the park is quiet outside summer season. There is no entrance fee.

The park faces ongoing challenges from eutrophication driven by agricultural runoff from mainland Uusimaa, which promotes algal growth in sheltered bays and reduces water clarity. Invasive species including the signal crayfish and round goby are spreading through the archipelago. White-tailed eagle recovery has been a major conservation success, with the Finnish population recovering from near-extinction in the 1980s to several hundred pairs today, aided by legal protection and reduced organochlorine pesticide use. Metsähallitus actively manages island meadows through restoration grazing to maintain open coastal habitats for rare plant species. Climate-driven changes in sea ice extent are altering habitat availability for ringed seals.
