Something fishy going on here
Barcelona’s aquarium may no longer claim to be the largest in Europe, but it's still a fun day out watching its 11,000 sea creatures, covering 450 different species. The show-stealer is the vast central tank, encircled by a 225ft viewing tunnel equipped with a slow human conveyor belt and serenaded by gentle New Age music; the patterns of silvery fish and sharks swimming all around and over your head are remarkably soothing. Kids can enjoy the interactive exhibits.
Love sharks? Qualified divers over age 18 can take a class on sharks on Wednesdays and weekends, then dive in their tank. The €300 fee includes a guided tour of the aquarium for you and two friends, all equipment and insurance.
