The Aare is the longest entirely Swiss river, flowing for about 295 kilometers through some of Switzerland's most picturesque landscapes, including cities like Bern and Interlaken. It originates in the Bernese Alps and eventually joins the Rhine River. The Aare River is a beloved destination for outdoor activities, including swimming, rafting, and kayaking. In Bern, locals and tourists alike enjoy swimming in the crystal-clear waters of the river, especially during the summer months when the flow of the river is calm and controlled by dams.

The water temperature in the Aare varies significantly throughout the year. During the summer months, water temperatures can rise to around 18°C to 22°C (64°F to 72°F), making it perfect for refreshing swims.
