"Swimming Along Zurich's Old City Wall This is river swimming at its most civilized. Zurich’s oldest badi, the men-only Männerbad Schanzengraben, is tucked away near the stock exchange and surrounded by the ivy-draped old city wall (you’ll miss it if you don’t look for it). Come evening, the badi transforms into the popular Rimini Bar, where both men and women mingle on floor cushions and rugs lining the pool’s edge."
