How do we use the free Un Mar de Jocs play area?

It's on the ground floor next to MediaMarkt. Before your first visit, register your child (ages 4-12) in the Diagonal Mar app to get a QR code, then show it on arrival. Stays are capped at one hour per day, and under-4s can come in with an adult.

When is Un Mar de Jocs open?

Monday to Friday 17:00-20:00, and Saturdays and public holidays 12:00-14:00 and 17:00-21:00. The wider mall is open Monday to Saturday 9:30-22:00 and Sundays/holidays 12:00-20:00.

Is it easy to reach by public transport?

Yes. The El Maresme | Fòrum metro stop (L4) is about a 3-minute walk, and there's a bus stop right outside. Parking is free for the first three hours.

What else is there for kids beyond the play areas?

A Cinesa multiplex cinema and the Ilusiona bowling and arcade complex (with VR and games) on the top floor, plus the open-air La Terrassa del Mar terrace with its El Mar and El Far play structures.
