Avesta Visentpark, also known as Avesta Bison Park, is a significant wildlife conservation centre located just outside the town of Avesta in Dalarna, Sweden. The park is home to approximately 30 European bison, also called wisent, one of the continent's most endangered large mammals, which roam in two herds across a large natural enclosure. The herd's history at Avesta dates back to 1939, and by 1965 the park had become the world's largest European bison breeding station. Today it remains one of the most important breeding centres in Northern Europe and is a partner of the European Bison Conservation Centre. Visitors can observe these impressive prehistoric-looking animals from the enclosure pathways, enjoy refreshments at the barn café, and let children play in the outdoor family area with swings and climbing structures.
