Barcelona is a beach city, that's part of its charm. The seaside is great for spending time outisde, enjoying the sunny weather and admiring the horizon in the sea.
Port Vell is a great place to do all of the above. It's a harbour in a really central location in the city where you can watch the boats coming and going, ride a bike, have some ice cream or even nice meals at the commercial center.
There's also an Aquarium there to amuse the kids and adults who love sea life.
