Åresjön, Lake region in Åre, Sweden

Åresjön is a lake in Åredalen, Jämtland County, at 372.4 metres above sea level, with Indalsälven as both its main inflow and outflow. It covers 6.4189 square kilometres, averages 9.8 metres deep and reaches 19.2 metres at its deepest point. The European route E14 and the Mittbanan railway run along the northern shore through Åre, and Åre Ski Area lies on the northern bank, with Åreskutan and Renfjället rising on either side of the valley.

The lake was formed during the last Ice Age as glaciers receded across the Scandinavian landscape. Local communities have relied on it for fishing and as a resource for sustenance and trade for centuries.

Ice racing and snowmobile tours take place on the frozen lake in winter, while kayaking and fishing replace them in summer. Ice skating has been a winter activity here since the 1920s, when ice racing competitions were first held in Åre.

The E14 road and the Mittbanan railway run along the northern shore through Åre and smaller settlements, giving direct access to the lake. Åresjön freezes from late November to early May, so winter visits allow skating on the ice. Åre Ski Area sits on the northern bank, with Åreskutan and Renfjället rising on either side of the valley.

During winter, the lake's surface freezes solid and becomes a natural ice skating rink used by locals and visitors for winter sports. This seasonal transformation is a notable feature that draws winter enthusiasts to the area.
