Enjoy Cósmico Rooftop

Cósmico is the rooftop pool club of the SLS Barcelona hotel, on the sixth floor at Carrer de la Pau 2, by Port Fòrum, in Sant Adrià de Besòs. It has two infinity pools facing the marina and the skyline, sunbeds and cabanas, and an all-day menu with Japanese and pan-Asian touches. It works in summer only: in 2026 it opened on 2 June, ran Cosmic Affairs parties on Saturday evenings and tardeos, and is now closed for winter, with a return planned for the 2027 season.

Dress Code & Entry Requirements

Cósmico doesn't publish a dress code or a minimum age on its website. Some events had their own code, such as the all-white party in August 2026.

A summer rooftop by the Fòrum

Cósmico opened in 2026 as the SLS Barcelona's new rooftop: it announced "Opening June 2nd" in May and opened on that date as a pool club and restaurant. Its website describes two infinity pools with views of the marina and the skyline, and a pool club built around sunbeds, cabanas and premium sunbeds for two. The menu is all-day and shareable, with salads, bowls, crispy chicken, sushi and rice bites, plus cocktails, smoothies and champagne. In July and August it was open daily from 12:00. The evening programme changed by night: some evenings were tardeo-style, with easy drinks and music, and others brought DJs and local collectives. It's a hotel rooftop rather than a club, and a summer plan only.

Cosmic Affairs and the 2026 season

The parties of the 2026 season were the Cosmic Affairs, on Saturday evenings. The first one, on 20 June, coincided with the OFF BCN Week, around Sónar, and brought two electronic labels to the rooftop for a day-to-night session with a secret international line-up. In July the club advertised them every Saturday from 18:00 to 23:00, with music, cocktails, sushi and the sunset before the dance floor took over. It also ran tardeos on Fridays and Sundays from 16:00 to 22:00, a Sant Joan evening on 23 June with a DJ until midnight, an eclipse night on 12 August with eclipse glasses, and an all-white party in August to close the Cosmic Affairs season. Its last dated event was Taste of SLS on 5 September 2026.

Closed for winter, back in 2027

Cósmico is closed now. Its Instagram bio reads "closed for the season" and its website says it's closed for the winter and expects to reopen for the 2027 season, without a date. In 2026 it opened on 2 June, so a similar date is likely, but treat that as a pattern, not an announcement. When it reopens, it books sunbeds, cabanas and tables through its own website. We don't sell anything for Cósmico while it's closed: if you're planning a birthday, a group day by the pool or a summer event for 2027, message us on WhatsApp and we'll get back to you as soon as the new season is announced. The rooftop is on the sixth floor of the SLS Barcelona, at Carrer de la Pau 2, next to Port Fòrum.
