We decided to visit this park (metro Botanicheskiy Sad/ Botanical Garden) based on other reviews. To our surprise we didn't find this place as traditional Botanical Garden. Most locals (unless they live in this area) does not know about existence of Botanical Garden in Karkov and does not consider this park as a Botanical Garden. I also don't understand why other reviewers mentioned tickets. The entrance is free, and it's mostly a local park where at the summer time people of all ages were spending their evening. What is really highlights this park is a natural cold water spring, where people were filling canisters with drinking water. It also has a small pool in the form of cross right across the Wooden Church on the hill (at the time of out visit it was under renovation). I guess that pool used for church baptisms, but at other time during the summer people just using it to cool off. Hiking trails were looking deserted (and kind of scary), so we didn't dare to hike there. In my opinion, unless you are in the area, it does not worth a special visit. But if you want to experience local (not touristy) life - go for it!
