Arosa Badi (Lido) Untersee

While general swimming areas of Obersee and Untersee are excluded, the Arosa Badi at Untersee provides a supervised bathing facility during summer. It features dedicated swimming zones, a children's play area, sunbathing lawns, and often a kiosk for refreshments. It's a popular spot for families to enjoy the lake in a safe and regulated environment, distinct from informal wild swimming. Entry fees typically apply, usually a few Swiss francs per person. Open during summer months, weather permitting, generally from June to September.
