Secret Underground X-Treme Fetish 2026

X-Treme Fetish returns to Ultimate Dream in Beek en Donk on Saturday 22 August 2026, from 20:00 to 03:00. It is the edition Secret Underground positions against the rest of the market: commercial fetish and kinky parties, the organisers argue, come with restrictions — and this concept is built without them.

The venue is a swingers club with a large new dance and play area, and for one night it is rebuilt into what the organisation calls the finest underground playground in Europe for fetishists, sensualists and kinksters: dance in one part of the room, play in the other, with the darker corners of the club in full use. The sound is the house style — driving techno mixed with the SU Sound — and the crowd is the mix this organiser consistently draws, from committed fetishists to erotic clubbers who simply want somewhere with no brakes on it.

The dress code is published per concept on the organiser's own dress-code page and is applied at the door, so read it before buying rather than after. Tickets are sold through Secret Underground's ticket page; this organiser sells across several editions at once, so check you are buying for the right date and venue.

Note the venue detail: Ultimate Dream is at Willemstraat 9B in Beek en Donk, North Brabant — not to be confused with the club of the same name elsewhere in the country. Parking is at the club.
