• Floating Rambla de Mar bridge that swings open for boats, a fun walk across the water to reach the entrance
• Free indoor play area on the upper floor, handy when the heat or rain makes the harbor unpleasant
• Open every day, 10am to 9pm, including Sundays and public holidays when most of the city shuts

Maremagnum sits on its own island in Port Vell, reached by the Rambla de Mar wooden swing bridge from the Columbus Monument. Two floors of shops and a food court wrap around an indoor atrium, with a free children's play area, an information point, and a first-aid room. Waterside terraces look out over the marina, and L'Aquarium is next door.
