Swingertreff Fiagra is a couples club at Dornstadt, just north of Ulm. It describes itself as a Pärchentreff for couples with an interest in FKK and partner swapping.

The house is small and the club names its rooms individually: a sauna, a mirror room and a fireplace room. It keeps an unusually full week for this sector — Tuesday and Thursday afternoons, Friday and Saturday late, and Sunday afternoon into the evening.

Sunday is run as a wellness day rather than a party: sauna, swimming, massage and brunch. There is also a Youngster-Party on the last Friday of each month, which runs to four in the morning.
