Crazyland is one of the longest-running fetish party organisations in the Netherlands, based in the Zaanstreek just north of Amsterdam and best known for B.I.T.C.H., the party it presents as the number one fetish party of Holland. The organisation celebrated its twenty-fifth anniversary in February 2025, which places its beginnings around the turn of the century — long enough that its parties are a fixture of the Dutch scene rather than a promoter's experiment, and long enough to have built the mailing list that empties its ticket shop months ahead of the door.

Its home is North Sea Venue on the Hemkade in Zaandam, an industrial events hall on the water that Crazyland fills with six separate play and dance areas: dance floors, staged performances, heavy decoration built to the theme of the edition, and dedicated play spaces with lockers and changing facilities. The scale of the building is the point. Where a club night works with the rooms it has, Crazyland dresses an empty hall from scratch for each edition, which is why its parties are announced by theme as much as by date.

Four concepts run under the Crazyland name. B.I.T.C.H. is the flagship fetish party, held more than once a year and split into editions with their own themes, including a recurring Classic. Crazyland Dark Circus of Pleasure is the dress-to-impress dark-circus edition, where the costume brief widens from fetish materials to sinister-carnival theatre. Sincity is a collaboration with Outlaw Events held on Amsterdam festival grounds, and the Crazy Wonderland Festival takes the format outdoors in summer.

The house rules are strict and consistently applied. Entry is 18+ and dress code is checked at the door — lacquer, leather, rubber, latex, PVC, metal, or the theme of the edition; street clothes are turned away. Men are admitted only in the company of their own partner, and that is verified rather than assumed. Doors also close early relative to the closing time, so late arrivals are not admitted at all. Tickets are sold in advance through Paylogic in tiers — early bird, couple, lady-only and VIP — and the popular tiers sell out months before the party.
