What is on at Flex on Halloween 2026?

Flex on the Donaukanal hosts The Hive x Collapse on Saturday 31 October, billed as “Face Off | Halloween Special” and listed under cafe party and club. Doors open at 23:00. The headliners are Magnetude (UK) and PRDK (CZ), with local acts listed in face-offs: Ced f2f DNBreak, Scapula f2f Weazl, Sinis f2f Lazaro, Mayez f2f Skeedz and Rellux f2f Distorted. Presale phase 1 is €9 and phase 2 is €15, sold through tickethead.io, and the door price is to be announced. Earlier that evening Flex lists a live show by TIAVO from 19:00, with doors at 18:00.

What is the Grelle Forelle Halloween line-up?

Grelle Forelle (Spittelauer Lände 12) lists “31/10 Halloween | The Tunegirl Live” with doors and box office from 23:00. The main floor has The Tunegirl live, Alex Maurer and Tezibel. The kitchen floor has DJ Bottleghost, DJ Veloziped and Altroy Jerome. Presale tickets are sold through Eventim and the box office sells tickets on the night. The page shows no price and no age limit.

Which Vienna club has Halloween nights on both Friday and Saturday?

U4 (Schönbrunner Straße 222) runs two nights. “Addicted to Rock – Halloween Special” on Friday 30 October starts at 22:00 with Niki Powernap (pop-punk and classics) on the main floor and Kev Black (nu metal and metalcore) on the club floor; presale is €10 and the box office is €15. “Halloween – Death by Sexy” on Saturday 31 October opens at 21:00 with four DJs playing pop, charts, hip-hop and “bad taste”, none of them named; presale starts at €13 and the box office is €26. U4 lists the Saturday as 18+.

What about Volksgarten and the other clubs?

Volksgarten links to “Halloween Weekend Tickets” on Eventim, but its website shows no dates, acts, floors or prices, so none are given here. Das Werk’s website could not be read for this post. Check each club’s ticket page before you plan a route, and use Vienna nightlife neighbourhoods to see which clubs cluster along the Donaukanal.

Is New Year’s Eve 2026 already on sale in Vienna?

At U4, yes. “New Year’s Eve 2026 – Let’s Go 2027” on Thursday 31 December has doors at 22:00, two floors (Party and Feel-Good) and is 18+. Early-bird tickets are €16 (entry until 23:00), €18 (until midnight) and €20 (all night), with €25 listed as a box-office price; the page shows a €30 tier whose meaning is unclear. Midnight brings gold confetti, a midnight waltz and a free “Welcome 2027” shot until midnight. Flex’s programme page and Grelle Forelle’s listing show nothing for 31 December yet. The Silvesterpfad programme for 2026/27 was not published on the pages checked. The 2025/26 edition ran from 14:00 to 02:00 across eight open-air locations in the centre plus the Prater, with a fireworks ban and more than 500 security staff.
