Barcelona is full of green parks which is a must for me in a big city. One of them I visit very often, Ciutadella, because it has a wonderful fountain and a lake. But what differentiates it from all the other parks is a statue of a life-size mammoth next to the lake. Apart from clicking pictures of this huge mammoth, this park also has a zoo to visit. There are beautiful lakes and museums inside to visit too. A great place to relax and learn!
