Club Adam & Eva is the largest swinger club Sweden. Located in Norrkoping, which is about 160km south-west of Stockholm, the club opened its doors in 1998. The club has nine playrooms, a modern wellness area (sauna included), a dance floor and, of course, a bar. It's a members-only club, so make sure to get your membership before you head there for the first time. If you are single guy, you may have to do an audition night in order to get membership.
