Prague Zoo. I want to note that the zoo is not only neat, beautiful and clean, but also thought out all the details to the smallest detail.
For example, there is a children's area, with a children's zoo and playgrounds where you can play with animals ponies, rabbits, ducks and others. In a lot of cafes, restaurants, souvenir shops. Since the zoo is huge, to get around, especially with children it's not easy, there are paths leading uphill. As a means of transportation, there is a cable car and a walking train that will take you around the perimeter
