Main image

Ängsö National Park is a small island national park in Stockholm County, Sweden, established in 1909 as one of the country’s first national parks to protect an open meadow landscape.

The park’s primary attraction is its managed hay meadows and grazing land, together with simple coastal scenery and short walking trails that circle the island. Visitors come for meadowland flora, birdlife and easy day trips by boat.

The park was created to preserve the traditional agricultural meadow habitat and the island’s cultural landscape shaped by centuries of haymaking and grazing.

Ängsö sits in the Stockholm archipelago in Stockholm County and is reached by boat during the warmer months; it functions as a small, day-visit nature reserve within the coastal archipelago.

  • Establishment (1909): Designated in 1909, it is one of Sweden's earliest national parks, created to protect an open meadow and traditional cultural landscape.

What to See #

  • Meadows: Open meadows maintained by traditional grazing and haymaking form the park's central feature and are the reason for its protection.
  • Shoreline and trails: Coastal shores and short walking trails circle the island and provide views over surrounding archipelago waters during the accessible season.

Tips for Visiting Ängsö National Park #

  • Go to Ängsö National Park in late May-June for the hay-meadow flowers and breeding birds; arriving early on weekdays avoids the bulk of summer day-trippers.
  • Reach the island by private boat or seasonal passenger boats from nearby mainland landings-check local summer boat schedules in advance, and use the designated landings to protect the fragile meadows.
  • Follow the marked paths and land only at designated spots; many visitors miss the traditional coastal meadows and nesting waders, so stick to routes to avoid trampling those habitats.
