About Bothnian Sea National Park

Bothnian Sea National Park protects a diverse archipelago of rocky islands, coastal wetlands, and rich marine habitats in the northern Baltic Sea, offering exceptional opportunities for boating, birdwatching, and nature exploration.

Wilderness Landscape & Natural Heritage

Bothnian Sea National Park, established in 2011, is located off the southwest coast of Finland in the northern part of the Baltic Sea. The park encompasses an extensive archipelago of around 98 islands and islets, scattered in the waters of the Bothnian Sea between mainland Finland and the western coast of Sweden. Its landscape is characterized by rugged rocky shores, shallow coastal waters, sparse pine forests, and sheltered bays, forming a habitat mosaic favored by diverse plant and animal species. The park is especially important for migratory seabirds and waterfowl, making it a prime destination for birdwatching. The marine ecosystems within the park support abundant fish populations, including pike and perch, which attract anglers. Visitors often reach the islands by private boat or guided kayak tours in the summer months, allowing access to pristine and relatively untouched environments. Hiking is possible on some of the larger islands where trails highlight the natural and cultural heritage of the archipelago. The park's surroundings also contain traditional coastal fishing villages that add historical context to the natural setting. Carrying a strong conservation mandate, Bothnian Sea National Park plays a significant role in protecting the northern Baltic Sea’s unique aquatic habitats and species. Seasonal weather includes cold winters when the sea freezes, enabling winter sports and ice travel in some areas. The park attracts nature enthusiasts interested in exploring remote island landscapes, observing marine wildlife, and experiencing Finland’s coastal wilderness.
