What Opium Barcelona Is Like: Music, Crowd, Dress Code and Age

Opium Barcelona is a beachfront restaurant and nightclub at Passeig Marítim de la Barceloneta 34, on the Port Olímpic seafront in Barcelona, Spain. It opens every night of the week, is 18+, plays house, EDM and commercial hits, and asks for smart dress: no sportswear, no flip-flops.

Restaurant by day, club by night

Opium has two lives. During the day and at dinner it is a restaurant with a terrace right on the sand and a Mediterranean menu. From around 23:30 the club takes over, and the club's own website says its events finish somewhere between 04:00 and 06:00 depending on the night. It sits in the row of seafront clubs at the Port Olímpic, between CDLC at number 32 and Shôko at 36, so on a busy weekend the whole promenade is full of people moving between doors. Time Out's October 2026 list describes it as a restaurant with a sea-facing terrace and 'a sophisticated club' with an international reputation, and recalls that it was ranked seventh in The World's 100 Best Clubs in 2023. In 2026 it is again among the Catalan clubs in the running for that list.

The nights: something on every day of the week

Opium's Instagram bio simply says 'Open every day', and the club's ticket agenda for the week of 21 October 2026 shows a different name for each night: 'Monday Madness' on Monday, 'Full Party' on Wednesday, 'Jet Lag' on Thursday, 'Addicted' on Friday from 23:30 to 06:00, 'Just Opium' on Saturday and 'Off Duty' on Sunday, which starts earlier (22:30) and ends at 04:00. Monday and Thursday are the nights with the most international crowd, because that's when the student and traveller guest lists point people here. For Halloween 2026 Opium runs four nights in a row, from Thursday 29 October to Sunday 1 November.

Music and crowd

Don't expect underground techno. Nightlife directories file Opium under EDM, commercial house and top hits, with some urban music, and Time Out adds R&B and dance. The club's site talks about 'hits' and international guest artists. The crowd is a mix of tourists, Erasmus students on the international nights and locals at the weekend.

Age and dress code

Opium is 18+, so bring a passport, DNI or residence card with a photo. Catalan law only bars under-16s from clubs; anything above that is the club's own admission policy. The dress code is one of the few that a Barcelona club actually publishes: Opium asks guests to 'dress elegantly', meaning dress shirts, blouses or fashionable tops and well-fitted trousers, skirts or dresses. Smart trainers 'may be acceptable', but flip-flops, beach sandals and sportswear (football shirts, tracksuit bottoms, gym clothes) are not, and the door can refuse entry to anyone who doesn't follow the rule. Coming straight from the beach in shorts is the classic way to get turned away.

What it costs and getting there

In October 2026 regular nights start at around €15 with a drink, as a guide price. Special nights cost more: for Halloween the listed prices went from €15 with a drink on Thursday and Sunday to €50 on Friday and from €35 on Saturday. New Year's Eve 2026 is announced from 00:30 to 06:00. The nearest metro is Ciutadella | Vila Olímpica on line 4. The metro runs until midnight Sunday to Thursday, until 02:00 on Fridays and all night on Saturdays; otherwise the NitBus runs every 20 minutes until 06:00. Catalan rules let clubs open until 05:00, and until 06:00 on Fridays, Saturdays and the night before a public holiday.
