Club El Diablo calls itself the exclusive alternative — an exclusive meeting place for open-minded adults, in its own words — and runs as a weekend swinger club at Uglerupvej 32 outside Holbæk, on Zealand about an hour from Copenhagen. Opening nights are Friday and Saturday from 21:00 to 04:00, with the club closed Sunday through Thursday.

The calendar is built from themed nights — recent programming runs from Naughty Night and a hot-tub Queen of the Night evening to an exclusive couples night, a Hardcore Swingernight and a Rainbow Night — each capped at around 150 guests with sign-up through the club's own site, where upcoming events and remaining places are published openly.

Membership works on attendance rather than fees: you register a free profile as a guest, it upgrades automatically to full membership the first time you visit and pay entry, and it lapses back to guest status if you stay away for three months. Members get access to the club's gallery, private groups, chat and event sign-up. Profiles are available for singles and couples.

Entry prices are published per event on the club's site rather than as a fixed list — check the event you plan to attend. Contact runs by phone or email, and the club answers within a day by its own promise. Browse our Denmark guide for the country's other swinger venues.
