Spain is a cheaper and great option in Europe to travel with kids. In Barcelona, kids aren’t necessarily welcomed but they are tolerated. You’ll find it difficult to find activities that specifically cater to kids but you are able to cart you kids around to pretty much everywhere so plan on seeing the sites.
Most of the metro stations have elevators, which make using a stroller easier. On that note, bring a stroller! Walking is the way to explore Barcelona, basically, so unless you want to carry your kids around the entire time, pack a stroller or plan to buy a cheap little one upon arrival.
Pick a hotel or apartment rental that is central in Barcelona. The city is very spread out and can save valuable walking time by being based in the middle of it all.
Things to Do
La Sagrada Familia
The Sagrada is visible from most parts of the city, and will help to peak the interest of the kids from the very beginning. The world famous unfinished basilica by Antoni Gaudi is covered in interesting architecture. The building is consistently under construction and for the construction loving child, this may entertain them for awhile. If you arrive early you can miss some of the crowds. Definitely purchase an audio guide, which will help to entertain the kids throughout the walk.
Parc de la Ciutadella
Home to the Barcelona Zoo, this is a perfect spot for kids. It features a giant mammoth, boating lake, waterfalls, massive fountain, playgrounds and even a band stand. You could spend a whole day here if you need to let the kids run around. Just keep in mind that there aren’t a lot of dining options in the park so bring your own picnic.
One of the most family accessible spots to visit, this monastery is a great day trip from Barcelona. There are two rides up and down the mountain, and some great mountain trails to explore the surroundings of the monastery. There is also a museum featuring works by Picasso and Caravaggio and of course the 1000 year old basilica to explore. For little kids, avoid going around 1pm, the Montserrat boys choir sings at this time and the area gets extremely crowded and the singing can get far too loud for little ears.
The park has two zones: the Monumental Zone and the free access zone. These buildings have incredibly unique architecture and are a great place for kids to explore. The buildings and grounds of the Monumental Zone are full of stairs, colors, twisting buildings and tiles galore, all great things to help kids explore.
