The river Sense (German: Sense, French: Singine) is a right tributary of the river Saane in Switzerland. It is a border river between the Cantons of Fribourg and Bern. Its source rivers, the Kalte Sense, coming from Mount Gantrisch, and Warme Sense, flowing out of lake Schwarzsee, join at Zollhaus and thus form the origin of the Sense.The Sense flows through a gorge of 15 km length, which is popular for whitewater sports, but also for swimming and bathing – especially among nudists.
