Microbuses and taxies from various parts of the Ferghana Valley go there. You can find those microbuses in near bazaars.
On foot or by taxie.
Amusuement park - ir is really nice little amusement park. The carousels are old type, but thats the whole fun of it. There is also a disco there, it is open during the day. There are also quite a lot cafes and ice cream shop!. Park looks really nice - green trees, some fontanos. All carousels are cheap. There is also special circus performance there. It is free of charge, but after each performance you can donate some money for the performers. It is very traditional and very interesting to see.
Certainly knives - there are merchants of knives in the bazaar.
Also try out variuos things in bazaar - there is this special sweet thing that looks like cheeze at first, but it is hard to chew. Nice taste and cheap price! Cheaper than you would get in Tashkent.
In the amusement park it is really worth to try some plov. The place is nice and you get to sit in these special outside eating ramps, traditional Uzbek thing.
