There's fun in the summer, but for half of the day fed up with it.Tsarina I now associated with something magical.There's a beautiful golden gates, as in the old TV show "In the animal world," only with more arms. At the entrance stands a saleswoman ice cream. Necessarily need to buy ice cream - it's like a ticket to a fairy tale, it is not without that experience. And straight to the singing fountain. There is a large park with squirrels, swans and ducks. Swans itself is fabulous. Yet in the middle of the lake there is an island with lush tree-like Lukomorie. It was a working day, so in the park there were few people and it was quiet, and the weather is great. Good then get a photo in the orange light of sunset.
