About Runn#

Runn is a lake in Dalarna County in central Sweden, located between the towns of Falun and Borlänge. It is a shallow, island-dotted lake used extensively for recreational activities across seasons.

In summer the lake is popular for sailing, boating and angling, and in winter it freezes sufficiently for organised long-distance ice skating routes and community ice activities. The shoreline is lined with small settlements, recreational facilities and campsites serving local visitors.

Historically the lake has been used for transport, local fisheries and timber floating; modern use emphasises leisure and outdoor sport. Management focuses on balancing recreation with conservation of water quality and shoreline environments.

Geographically Runn sits in the Falun-Borlänge area of Dalarna, well within central Sweden and easily reached from the adjoining towns that share its shoreline.

  • Recreation and seasons: The lake contains numerous islands and sheltered bays, making it popular for summer sailing, fishing and for long-distance ice skating trails in winter when it freezes.
