Gorky park is one of the famous parks in Moscow, I think. You have many possibilities there, for example, you can go for a walk there and seat near the fountain. Also, you can play table tennis or ride on skateboard, if you have it. in winter, there is a big skating-rink, where you can skate a lot. well, to my mind, it's a very good place for pastime. if you have some money, you can buy a ticket for riding on a steamer. it's interesting. sometimes Gorky park arranges different exhibitions and i think, it's very cognitive.
