Club-Karree is a swingers club at Philippsburg in the northern Karlsruhe district, off the B35 between Bruchsal and Germersheim. It runs on a party calendar — couples' and ladies' nights, pool parties in summer — and publishes a guest list, a dress code, house rules and a page written specifically for people coming for the first time.

The club makes a point of its own standards, selecting its guests and setting out what it expects of them, and it has been given a five-star premium rating by JOYclub. There are concessions for students, apprentices and guests under 25 on production of ID, a smoking area, and overnight accommodation.
