Located south of Prague, Podoli bath is a popular swimming pool in summer for local gay people of Prague to come to on week-ends. Most of it is just a regular swimming pool frequented with families. But yu have a naturist sunbathing area and a sauna. Both are especially popular for gay people , exchange looks and getting horny together. Just make sure you remain discreet enough as it's not an official gay cruising area. For real action I would choose the take away option, or the privacy of a toilet's cubical if it's not too busy.
