The area is recognized as one of Sweden's most important inland birding sites, hosting over 200 species throughout the year.
The park serves as a natural flood barrier, helping to regulate water levels between Lake Hjälmaren and the city of Örebro.
In the early 20th century, parts of Rynningeviken were utilized as a limestone loading site, remnants of which can still be found in the terrain.
Grazing cattle are used as a primary landscape management tool to prevent the wetlands from overgrowing with scrub and trees.
The park contains a specifically designed 'bird window' that allows photographers to capture wildlife without disturbing the ecosystem.
Oset and Rynningeviken is a expansive nature reserve situated along the eastern shores of Lake Hjälmaren in Örebro, acting as a critical stopover for migratory birds. The area features a complex mosaic of wet meadows, reed beds, and old pastures managed through grazing to preserve biodiversity. A network of accessible wooden boardwalks and gravel paths spans the wetland, allowing visitors to traverse directly over marshy terrain. The site was once an industrial harbor area before being restored into a recreational parkland for public use. It serves as a vital ecological corridor connecting the city center directly to the wilder landscapes of the lake's archipelago.
The elevated wooden bird-watching tower located near the center of the Rynningeviken trail loop.
Bring binoculars, as the elevated watchtowers provide visibility across the vast reed beds for long-distance bird spotting.
Stick to the marked wooden boardwalks, especially during spring thaw, to avoid sinking into the soft wetland soil.
Check the local wind direction before visiting, as the open landscape along Lake Hjälmaren can be significantly colder than the city center.
Attempting to walk off the established trails during spring, as the ground becomes extremely waterlogged and boggy.
Paths may be partially flooded or inaccessible during high water levels in late spring.
Leash your dogs at all times to protect ground-nesting birds; do not pick flowers or disturb grazing livestock.
